Irssix 0.2 Description:
Irssix is a fast, snappy, and free IRC client for Mac OS X. It offers easy keyboard navigation, tabbed chatting, color, regular expression searching (line limiting), and an intuitive interface. This beta version does not have all GUI dialog boxes implemented yet, so it may be difficult for the user who has never used IRC before. Irssix is based on the code from the fabulous unix IRC client Irssi.
