Very good chat program. It's the only one I got to work trouble free that's free and open source. The others like hexchat gave me problems because of my internet security blocking it after the first successful run.
Finally, a free IRC client which is under _active_ development and which actually works!!!! It looks really nice, is slim and I am enjoying using it. Thank you for making this available! (Used on Windows 7, 30 April 2010)
