Warning #1: this web client is not very fun to use. If you can find a real MUD client, use the ifMUD java client, or even use a telnet program, that would be preferable. (Links to these can be found on the MUD's front page.) However, in a last resort, this is (barely) usable.
Warning #2: you must type quit to log out. If you just close the window, your character will stay on indefinitely.
Warning #3: this requires frames.
Warning #4: there's a 15-letter key in the URL of your page. Do not let anyone know what this is for the duration of your session. If you are in a place where you can't trust people looking at your screen, too bad.
