Fantastic program. I hunted for an OS X IRC client for a few weeks, trying out multiple completely different clients, to settle on jIRCii. X-chat Aqua has a laggy interface, other clients are missing features like auto-reconnect or other basic features. jIRCii is missing some GUI customizeability of other programs but it makes up for it in robustness and stability. It handles multiple servers, rooms, chats, files, and more, in an interface that's easy to pick up (although it doesn't hold your hand like some other mac IRC clients, which can be good or bad depending on your experience level). I had it set up and working EXACTLY like I wanted an IRC client to work in about 5 minutes. Perfect! And it's been great ever since. I'll be using this program for all of IRC needs for a very long time, and look forward to future features.
