Colloquy is hosted on SourceForge but the project appears to be idle and I can't reach any of the authors. For this, I decided to make my bug-fixed version of Colloquy available on this site.
Finally, I could get in contact with the original author. In the meantime, he brought Colloquy towards version 2.0.
Unfortunately, he rejected about all of my bug fixes and enhancements.
Colloquy 2.0 isn't any better regarding the problems I had with version 1.0. I'll let this site up, as the version on this site is still the only one working for me. Maybe for others as well.
Colloquy is a free, well designed, easy to use chat client, written in Cocoa/ObjC. Currently it supports the IRC protocol only and requires Mac OS X 10.2.0 or newer.
