There are a number of IRC clients available, here are just some you might like to try:
irssi - Command line client, can easily be run through a screen session allowing you to stay in the channel even when your desktop machine might be switched off.
XChat - Graphical client for Linux - there is also a download for Windows (the official site distributes their Windows builds as shareware).
