The deal with YW ff is, I have declared that I will write some this summer. Punkt. But it may take the entire summer to develop a plot that isn't fluff. So fic challenges will inevitably result in unsatisfying little things.
After summer, school will start again. Even the most efficient worker and active HP fan I know at college, flourish, stopped most of her involvement when real life got busy. So I have no hope.

BUT it sounds like a good idea to create a ficcing community. And I would join as soon as I had something to share.
