Growl is a great system wide notification system for OS X, and while some IM clients support Growl natively, others need a little help. iChat is one of those applications – once you start using Growl with iChat, it’s hard to stop. Instead of having to stop what you’re doing to see what your buddy is saying, the messages appear as Growl notifications. By installing a free program called “Chax”, you can enable various types of iChat Growl notifications, among various other helpful features. Check it out here.
