Notification when story is accepted; "tell me when this story is accepted" would be cool, too.

I would love it if I could get an e-mail when a story's accepted. The rejection e-mail is helpful, but it'd rock if Tracker would ping me when someone's signed off on a story after I've finished it.

And as to pie-in-the-sky ideas, I know a bunch of people here would love it if there were an "e-mail me when this story is accepted" button on every story, so you could have Tracker update you on stories that aren't your own.
