Some sort of communal thing where people talk about their WIPs & make a challenge to finish one (or more!) by a certain time, or whatever?

I think this is a great idea! The WIP Club! ;)

The story I'm working on right now is shaping up to be kind of gigantic, and I'm feeling kind of daunted. Having a space to discuss and work through problems with other people who are in the same boat would be epic.
