KARINA  Looks like it's shaping up to be a nice client, if it had the option of laying out servers/channels like Mice iRC it'd be awesome, so far that's the only layout I've found manageable with a high volume of server connections and channels and I prefer to have a minimalistic ui.

Seems to have issues with Austnet irc network, I can't join channels, message, ctcp, notice etc. Yes the connection is active and it works elsewhere fine, Xirc has similar problems with Austnet, I think maybe due to the virtual world system there.

AMON-RE  Great IRC client. I think I've found the one I have been looking for for ages! :)

It's still in development, but it looks great. I especially like the channel bar; it makes being on a lot of channels much easier. Crikey! is user friendly, and it looks cute.

Definitely worth a try!
