XChat

This is the best option if you are using pureydyne but are not comfortable working in a command line environment.

XChat is an IRC chat program for both Linux and Windows. It allows you to join multiple IRC channels (chat rooms) at the same time, talk publicly, private one-on-one conversations etc. Even file transfers are possible.

Documentation on how to get started with Xchat is found here:
