Do you know what is avatar meaning? hmmm..
Among people working on virtual reality and cyberspace interfaces, an avatar (sometimes AV or av) is an icon or representation of a user in a shared virtual reality. The term is sometimes used on MUDs, in computer role-playing games, and shared non-gaming universes such as Active Worlds, There, Second Life, and The Palace.

This definition has recently been applied to online virtual communities and Internet forums in particular, as a picture that a member/user of such a community/forum has elected to display alongside his or her contributions in order to represent him- or herself. Avatars have also become popular in instant messaging, and are sometimes referred to as buddy icons.
