A couple of years ago, I started this group as a writer's critique group. It died out after a couple of months. We tried again, and it died out again.
So I asked myself, "Self, what do you want to do with this place?"
Then I remembered svmadelyn's "Summer of Our Productiveness." For the summer of 2005, a bunch of fic writers formed teams and competed against each other to complete a WIP. It was awesome! It was fun! And I wanted to do it again.
But I didn't want to limit my challenge to just one story. I wanted to be able to work on more than one thing.
