Your terminal will receive a banner that welcomes guest/guest and you will be prompted to register a username.
If you chose to do so you'll be granted a (limited) UNIX shell, a solid Lisp environment (SBCL, Slime, emacs, Hunchentoot ...), 30MB of hard-disk space for your homepage and projects, an old-school BBS and all kind of services and games that you would previously have accessed with
telnet, (including a great MUD set in a cyberpunk universe.)
