Virtual community, e-community or online community....

A virtual community, e-community or online community is a group of people that primarily interact via communication media such as newsletters, telephone, email, internet social network service or instant messagescomputer network, it is called an online community. 

Virtual and online communities have also become a supplemental form of communication between people who know each other primarily in real life. Many means are used in social software separately or in combination, including text-based chatrooms and forums that use voice, video text or avatars. Significant socio-technical change may have resulted from the proliferation of such Internet-based social networks.

Virtual communities, or online communities, are used for a variety of social and professional groups interacting via the Internet. It does not necessarily mean that there is a strong bond among the members, although Howard Rheingold, author of the book of the same name, mentions that virtual communities form "when people carry on public discussions long enough, with sufficient human feeling, to form webs of personal relationships". 

An email distribution list may have hundreds of members and the communication which takes place may be merely informational (questions and answers are posted), but members may remain relative strangers and the membership turnover rate could be high. This is in line with the liberal use of the term community.

The embedding of virtual community in the experiences of everyday life and its reflection of and influence on the communication practices and patterns of identity formation make online community a colossal research enterprise which requires continuous investigation and theorizing.
