Dude, very, very cool. Very no-nonsense and easy to understand. That's a major bonus.

You might look at Basecamp (see the link in my signature) for some ideas for future development. I definitely wouldn't get too complicated, but they have some pretty cool ways of implementing team to-do lists, responsibility assignment, and collaboration on verbiage. It's a pretty cool tool.

Great job on the site! I look forward to seeing where this thing goes!
