A better procedure is to download a so-called 'client' program. Several popular clients are listed below. Pueblo Pueblo was published by the now-defunct company Chaco. It's available from the link at the bottom, to the 'executable'. After 2 weeks, Chaco may ask you to 'register'.
Pueblo is an excellent client, with good capabilities, and is very popular.
SimpleMU is a nice client. Like MUSHclient, it is shareware, and supports triggers, timers, and the like. If you're using a Unix-type system, you know what you're doing. You're capable of running the command telnet pangaeamoo.org 7777 without being told that's what you need to type. It supports all sorts of fun stuffs- triggers, et cetera.
