An online community is a virtual community whose members interact with each other primarily via the Internet. For many, online communities may feel like home, consisting of a “family of invisible friends."[1] Those who wish to be a part of an online community usually have to become a member via a specific site and necessarily need an internet connection. An online community can act as an information system where members can post, comment on discussions, give advice or collaborate. Commonly, people communicate through social networking sites, chat rooms, forums, e-mail lists and discussion boards. People may also join online communities through video games, blogs and virtual worlds.
