This is perfect if you want a shoutbox that is just a shoutbox - I don't need private rooms, or irc capability, I just need a place for my members to chat and this does the job well. It's well designed so I didn't feel the need to tweak templates at all, I could install and go. It runs very smoothly and my members like it a lot. Also there are some extra features you wouldn't expect, like ability to show the avatar of the person posting, and ability to have a sound play when a shout is posted.
