Thanks for the feedback, binaryWeapon. I've actually started on the site already, since I didn't want to make public an idea I thought I wasn't going to finish. I'm deliberately keeping the site small and simple, so that I can actually finish it

which means...at least until the 1.0 version, I'm planning on going it solo.
The forum would be a bit of an undertaking, since I'd want it to be fully integrated with the site, which is using ruby+merb. But hopefully it'll be coded by version 1.1
As for the projects that make it into the End Zone (heh), that does sound like a good idea, though I don't know how often projects ever reach a Done state. It could serve a similar process to the Graveyard, in that the creator feels like "I've done everything I'm going to do with this".
I've briefly considered actually hosting some of the code on the site, but...space is hard to come by on a VPS, so if I did it at all, it'd be like, 1-2 megs, maaaybe 5 megs maximum.
