I am still VERY new to Linux but...
I finally found a irc client that "feels" right. KVirc
http://www.kvirc.net/
I've tried xchat, bitchx, etc. but this is my irc of choice. Windows immigrants, mIRC users will like this one. althought it not exactly the same. It's alot easier to navigate then the previous clients I've tried.
the script archive for the client doesnt contain much (5 or so scripts?) . but it does support scripting.
so if your still looking for an irc client that feels right. check it out..
oh, I installed the newer kvirc3 thru a deb file on the site. when i clicked on the deb. kpackage managed it automatically. Sweet! i thought I had to learn dpkg command.

kvirc3 is working perfectly and running 24/7 with no issues. I didnt check if kvirc3 was obtainable thru apt-get / kpackage / synaptic.
I hope that helps...
It should work much better than trying to run Mirc in a Windows Emulator
