This is the best IRC client available for MacOS X, and free to boot! Many thanks to the developer for giving us his time and effort. There is a single feature I would like to request for the next revision, and that is support for the dccserver extension (part of mIRC, but ported as a source patch to xchat as well), as more and more fserves and xdcc servers are requiring it. I hope this gets added soon, as it would make this app a lot more useful. I can't really dock any points for the lack of this feature since it's a non-standard extension to IRC, but it is becoming more and more necessary to have.
