Based on the *nix IRC client irssi (http://www.irssi.org), MacIrssi is an powerful, free of charge, open source IRC client. It combines the power of the irssi engine with an elegant and flexible GUI. See also http://www.irssi.org/?page=about for information on the irssi engine.
What's new in this version:
- The text output problems that came with 0.6.2 are fixed!
- Only scrolls visible channels when receiving a message.
- An improved link-scanner, which also fixes some crash problems.
