TMI-2 is short for The MUD Institute 2. The MUD Institute was founded to create a new driver and MUDlib for aspiring creators of new LPMuds. It also existed to provide a forum for support and training of new creators. TMI-2, the second incarnation of TMI, was founded in February of 1992. Its major contribution to the LPC world is the MudOS driver. Of course, the TMI-2 MUDlib was also created, which became the basis for the Nightmare MUDlib, developed by George Reese. The physical TMI-2 server no longer exists, but the MUDlib is available on ftp.imaginary.com.
