93. Listservers, for example, can be set up on any network (or Internet) server by means of simple instructions given to one of several widely-available software programs (listproc or majordomo).

Cyberspace not only permits the effective delineation of internal boundaries between different online spaces, but it also allows for effective delineation of distinct online roles within different spheres of activity and as to which different rules apply. In the nonvirtual world, we slip in and out of such roles frequently; the rules applicable to the behavior of a single individual, in a single territorial jurisdiction, may change as he moves between different legally-significant persona (acting as an employee, a member of a church, a parent, or the officer of a corporation, for example). Cyberspace may make the boundaries between these different roles easier to maintain, insofar as explicit "tags" -- distinct "signature files," or screen names-- can relatively easily be attached to messages originating from the author's different roles.
