So....if you guys want to work on the project together, I'd suggest using box.com as well. It's great for file sharing and discussion of the project, kind of like a mini forum. Once you make a box.com account, state the e-mail/username you signed up with and I'll add you to the community project group, where we can download, judge, and provide criticism for each other's levels.
If you aren't in the community project but want to take a look at a level I'm implementing, here's the first one I've finished. It's actually from quite a while ago, but it didn't really get that much attention:

We could also set up times where we can work online together like how SMB suggested, so I'll make a discussion thread for that in the group on box.com.
