Maybe someone on our IRC channel might be able to help you get started. Make sure you let them know which world you were trying to enter.

Our channel is called #ABNet running on irc.freenode.net

Any IRC program should work. On a PC you might want to try mIRC from http://www.mirc.com/

Once you have that installed try this link:
