1. Introduction
Since early 1980s, virtual communities have existed on the Internet in the form of Usenet newsgroups. These communities and the accompanying research have recorded exponential growth with the advent of the World Wide Web. Virtual communities form as a result of common interest among individuals and groups to discuss for example, a hobby, a common past experience, or enduring a disease common among the group members. Scholars generally agree on the characteristics that are associated with a virtual community (Stockdale, 2006). For example a virtual community is comprised of members who share an interest, interact repeatedly, generate shared resources, develop governance policies, demonstrate reciprocity, and share cultural norms (Preece, 2000). However, the actual definition of the term “virtual community” often differs based on which individuals join or visit a community (Lee et al, 2003, Preece, 2000). For example, the earliest virtual communities tended to focus on member’s social interests, many more recent virtual communities focus on member’s commercial interests (Kannan et al, 2000).

The meeting place in everyday life can be equated to a web portal on the Internet. The underlying technology is supported by email lists, newsgroups, chat rooms, message boards and bulletin boards. The members of the virtual community form strong relationships. These personal bonds sometimes translate into deep community attachments (Hiltz, 1984; 1997). These interesting community attachments form despite the typical limitations of computer communications, notably the absence of personal interpretations from tone and voice, dress, physical attributes that are all missing in the virtual world . Despite these limitations, the community relationships have been seen to flourish based solely on the conversation through the cyber space. The key element in the building of these relationships is the element of trust that exists among the members. Trust has an effect on the members to exchange information through the virtual community (Ridings et al, 2002).

This paper examines the virtual communities on the Internet, those that form without a formal approval from a government body or organization or for that matter any person for an expressed academic or economic interest. Interest groups, for example, a group of men fighting the prostate cancer sharing their experiences and concerns in a virtual environment is a typical example of a virtual community for the purpose discussion in this paper.

2. Cultivation of Trust in Virtual Communities
There is no consensus regarding the concept of trust (Gefen et al, 2003), but most agree that certain beliefs, such as integrity, benevolence, competency and/or judgment, reflects one’s trustworthiness (Doney and Cannon, 1997). In a social relationship, trust is an important ingredient. (Blau, 1964). The multidimensional concept of trust has to do with the beliefs of skills/expertise of the trusted person have in a certain area. Ability relates to the belief that the other person knows what he or she is discussing. Since virtual communities are concerned with focusing on a particular topic at one time, this trait is particularly relevant. Benevolence is concerned with the expectation that others would have a positive desire to do good to the person entrusted with the information. It is expected that the trustee would reciprocate with advice, help guidance and intent to support the ongoing discussion. This is particularly important in virtual communities since without positive reciprocating response, the community may cease to exist. Integrity in the context of virtual communities implies that the members will act in accordance with socially set values of honesty like refraining from telling lies and providing verifiable information.

One of the definitions of trust is the willingness to take a calculated risk based on someone‘s behavior (Mayer, Davis, & Schoorman 1995). It has also been defined as a means to reducing social uncertainty (Gefen, Karahanna, 2003, Luhmann, 1979). In the context of virtual communities, trust is used to reduce the level of social complexity associated with the behavior of other members. It also employs to reduce the fear that the other member may take advantage by engaging to cash the opportunity if it exists (Gefen et al, 2003), much in the same way as it does in communities in everyday life (Fukuyama, 1995).

Trust is a critical element in a virtual environment (knoll, and Leinder, 1998). The confidence and the feeling of security can be enhanced among virtual team members through trust. It also promotes confidence and security in addition to promoting open information exchange.

The computer based interaction eliminates the traditional experience of feeling the warmth and attention and of course trust. Lack of direct face to face contact in computer communications may have a negative impact on the understanding of a communication sent across the network. It has been found that electronically communicated information is relatively difficult to comprehend in a discussion among virtual community members (DeSanctis and Monge, 1999).
Individuals also take longer to form opinions about others on a computer medium as it takes longer to decipher social codes (Sproull and Kieser, 1986). In essence, the extent and type of cultural variations represented on the virtual team make a difference in the formation of trust.

There is risk involved in the interaction in a virtual community. Selling personal information for example could be classified as an opportunistic behavior. Assuming a false personality, marketing products and services, spamming, making jokes at members, and behaving in a manner that breaches the trust of the community members all fall under this category.
These traits are common in other types of communities too, but in the case of a virtual community, it is relatively easier to hide the intentions and accomplish such behavior by the crook and much harder for the victim to notice.

3. The Ingredients of Trust
In everyday life, trust between members of community develops by successful interaction (Blau, 1964; Gefen, 2000; Luhmann, 1979). In a virtual community trust is built through a number of mechanisms that are typical to the on line world. The responsiveness of other members of the community is essential for the trust to develop (Ridings et al, 2002) along with adherence to social norms. When members of online communities post a message, they subconsciously look for a reply to be posted by other members. In case of late or no response, or a response lacking in number, there is no successful interaction resulting in the reduction of mutual trust among members. If members regularly read what other post on the board, they contribute to building the trust. If others post personal information, they appear more friendly and less as strangers thus contribute to building trust. Personal information can also be provided in site profiles in the form of email address, age, gender, name or a personal problem and it may add the credibility of the member (ability virtue). This will make it easier for other members to form beliefs about following community standards and set of values (benevolence and integrity). Thus providing personal information also contributes to building trust among virtual community members (Riding et al, 2002).

Disposition of trust is the general willingness of people to depend on others to some extent (McKnight, Cummings, 1998) which has been found to be uniform across a range of situation and scenarios (Meyer et al, 1995). People do not know each other in the initial period of interaction with each other in a virtual community. Therefore, disposition of trust is also an important factor culminating in the building of trust among members. Empirical studies have found that disposition of trust is directly related to trust in a virtual environment (Gefen, 2000, Jarvenpaa, 1998). This is true in a virtual community (Ridings et al, 2002).

An honest behavior in a virtual community is the key for successful interaction among members. However, there is no legal framework to enforce appropriate conduct in virtual communities. The feeling of being part of a community and its membership may provide a possible way to enforce honest behavior. A trusted third party certification mechanism helps enhance honest behavior in virtual communities (Ba, 2001, Ba, Whinston, & Zhang, 2003). Although there are three trust building mechanisms in the virtual world, namely feedback, insurance/guarantee and escrow, extralegal framework if adopted, will be particularly useful in virtual communities. Community appreciation, gossip and reproach being part of the extralegal mechanism may serve to create trust as they do in regular social environment.

According to Ba, virtual communities may build trust through the sense of community (Ba, 2001). This is particularly relevant when there is time between the quid and the pro. If the concept of accountability is introduced, there will be more social pressure to adhere to the rules. AN example would be if the members of the community are held responsible for the actions of an offender. This approach might only work with a strong sense of community, and many virtual communities do have a strong sense of community participation among their members.

Another area which demands trust is the user privacy. Many virtual communities discuss issues related to personal topics, like legal issues, medical conditions, or occupations. The participating members may choose to be anonymous while taking part in discussions. However, this might have an impact on the sale of advertising space or products to users. The emphasis is then placed on the provision of user statistical data that involves demographics and email addresses, which is a trade off against the settings of user privacy. It may be viable for the virtual communities to incorporate procedural fairness to be seen by the members as a fair way of collecting personal data for statistical purpose.
Procedural fairness has been found to address the protection of personal privacy concerns and helps build trust that customers need for an organization for marketing purpose (Culnan & Armstrong, 1999).

4. Building Trust through Communication
Communication processes form the basic mechanisms that help enhance the trust. This is attributed to the fact that information carriage provides details about the personalities of virtual team members, helps in forming common goals, and aids in continued interaction through computer medium.

Communication among members is an essential characteristic of trust in a relationship (Kanter, 1994). The success of a relationship tends to suffer if there is a lack of communication among the community. The members need to constantly interact with each other to smooth out their differences, and form a smooth relationship free of kinks.

Since members need to collect evidence about other fellow members trustworthiness, communication is the only way that such a process is facilitated. It results in information asymmetry (Hart and Sauders, 1997)

Communication further develops trust among members because it provides the frame work for a continued interaction, from which members further solidify their links. Members tend to identify common interests and norms reinforcing a sense of trust.

4.1 Effect of Cultures in a Communication Process
The degree, to which the cultures of two parties communicating with each other are similar, has a bearing on the understanding of the conveyed message. The greater the differences in cultures, greater the difficulty in understanding the message. These cultural differences are more effective in the first two phases of the communication process when messages are assembled and transmitted and are then acquired by the receiver who interprets and responds to them (Gibson, 1996).

Messages also vary in nature with respect to the extent to which they contain contents based on facts rather than highly emotional material based in personal experiences and intuition (Glenn, Witmeyer, and Stevenson, 1977). This inference is based on the fact that cultures vary in the extent to which they lay emphasis on irrational thinking and communal values.

5. Future Directions
With basic understanding of trust in a virtual community, the future research may investigate multiple directions of this important ingredient in an ever evolving domain of virtual communities. It could be a possibility that the trust develops differently in different kind of communities. For example, the trust deficit faced by a virtual community interacting in the subject of prostate cancer may be different than the level of trust experienced by a virtual community discussing cricket as there are different attributes involved with the nature of subject being discussed/interacted with. The level of trust for an individual varies with his level of association with the community. This could be an area of investigation to quantify the level of trust. Variables such as race, age, gender, and culture may also influence trust and its development (Gefen, 2000b). Studies of virtual communities may provide more insight about the development of trust over a period of time.

6. Conclusion
With the advent of World Wide Web, virtual communities have evolved to be an effective medium for meaningful interaction by community members for the exchange of information. These venues also provide interactivity to website sponsors on the Internet. For virtual communities to grow, they ought to have conservation, which is derived from trust among community members. Trust in other member’s abilities is essential as well as in their benevolence and integrity. Trust has been found to be enhanced by member responsiveness, confiding personal information, and the disposition of trust by a member.
