One of the best IRC clients in a long time!

Having used Linkinus, LimeChat, and many other OS X IRC clients, this one is by far the best one. Subtle colouring, integrated full-screen support for Lion (and no crashing!), and ease of use makes this my favorite IRC client. Even though there are no preference to set, you really dont need to set any - it has everything you need out of the box for basic IRC uses.
