Okay, as one of the not-that-old members, that site is missing one crucial piece of information.
Why should I care about this project?
More to the point, why should I want to join a project where all the fun bits of working on a project (namely, the creative ones), have already been done and locked?
I am sort of missing a sense of excitement here, a feeling of "Yeah, I want to be part of this because it's awesome, and it could be more awesome with my help".
I know you don't want to hear this, but if you had released something where someone such as I can see what this is about, and see where my skills could be of use here (like, say, a demo. Or a video. Or the campaign.), this project might be more appealing.
