According to Wikipedia (retrieved 12:34, 12 April 2007 (MEST) and with original links): An online identity is a social identity that network users establish in online communities. Although some people prefer to use their real names online, most Internet users prefer to identify themselves by means of pseudonyms, which reveal varying amounts of personally identifiable information. In some online contexts, including Internet forums, MUDs, instant messaging, and massively multiplayer online games, users can represent themselves visually by choosing an avatar, an icon-sized graphic image. As other users interact with an established online identity, it acquires a reputation, which enables them to decide whether the identity is worthy of trust.
See the digital identity article for issues related to on-line identification and authentication.
