http://braintrust.io is targeted for teams. It's not about project management, its about idea and conversation management within teams (a.k.a. we're not another 37signals-copy-winning-basecamp solution).

I've created http://braintrustcommunities.com -- which is designed for public communities like HN (based on the same platform) -- alas, I'm a single founder, and haven't gotten around to making the rest of the copy updated yet. I'm hoping to kick off a private beta of Communities over the next few weeks for Braintrusts that are public.

If you're truly interested in getting this going, lets chat and we can make it happen.
