I just found this and thought it could be useful tool in keeping track of game projects, especially for group projects. The screen cast was very impressive -- it looks easy to use and would be a good way to organize a game projects work flow. Anyway you can check it out here:

Thanks for posting this!
It looks like it should be very helpful, especially considering how disorganized I am half the time... :P
Edit: Just finished reading how to use the entire thing, and it looks great.
