The difference between a MUD and a chat room is that in a MUD, you can create objects with which you and others can interact. Multi-User Domain, Object Oriented.
MOOs are descendants of MUDs and are typically either socially or educationally oriented.
In a MOO, there are typically fewer magic wands and dragons than there are libraries, poetry rooms, and classrooms. We will be usingan educational MOO called Lingua MOO, which is located on the mainframe at the University of Texas at Dallas. In this seminar room, we will hold class discussions, conduct presentations, carry out group work, etc. In this virtual space, in other words, our techno-selves will conduct class pretty much as usual. Embedded texts that feature hot words.
