I direct your attention to these two threads:

http://www.escapistmagazine.com/forums/read/18.110578-The-Short-Story-Thread
The first of those is slightly necroed, but that's simply because it's a unique and original idea that sadly no-one cares for, because everyone is too busy bumping up their post counts by complaining about the lack of original threads to bother actually posting on those threads when they do, regularly, appear.
Anyway, if you're interested in creative writing, those are both great places to go (and threads I myself frequent, solely because of my own enjoyment of and talent for creative writing).
