I’ve been using Growl for sometime now and it just got updated to 1.1.1. If you haven’t tried Growl, you should. It installs a universal notification system that talks to most of the frequently used apps on your Mac. Then when any significant system event occurs, it pops up a notice in the format of your choice. I like the “music video” format the best. Growl is unobtrusive but informative. I know when my ftp is done, when I receive new mail, and a host of other events of interest. If you haven’t got it already give it a try. You can download it right here.
