More little (and free) mac apps that I am trying. Playing with Growl. it is a simple unified notification system for multiple mac apps. If it is as cool as what I have seen so far it is a nifty notification engine for several apps I already use. if it is not, it can be an annoying pop up window. So far it is good. Actually half the reason I am posting this now is to see what Growl does when I post using Ecto.
