Nice new tool

Didn't know where else to put this, so it's going in Opinions. Saw some posts about Power Tab and Guitar Pro and it reminded me about this site I ran across Monday. http://www.noteflight.com . It's not a tab site or anything, but it's basically Google Docs for music composition. Your stuff is saved online and you can share or collaborate with others. It's got all the midi instruments and such, just like Finale and the other very pricey software packages. I haven't composed anything yet, but it will be handy if I get a melody in my head at work.
