There are over 300 multi‐user games based on at least 13 different kinds of software on the international computer network known as the Internet. Here I use the term “MUD “ to refer to all the various kinds. All provide worlds for social interaction in a virtual space, worlds in which you can present yourself as a “character,” in which you can be anonymous, in which you can play a role or roles as close or as far away from your “real self as you choose. In the MUDS, the projections of self are engaged in a resolutely postmodern context. Authorship is not only displaced from a solitary voice, it is exploded. The self is not only decentered but multiplied without limit. There is an unparalleled opportunity to play with one's identity and to “try out” new ones. MUDS are a new environment for the construction and reconstruction of self.
