(Rules are from the Watchmen Kink Meme, with minor edits, because they're pretty darn good rules.)
1. Anonymously post a pairing and prompt you would like to see written. Since this is a kink meme, there is supposed to be a kink involved, but well-written gen prompts should work just as well.
2. Anonymous will respond to your post and write it for you! Art is also acceptable. Multiple people may respond to the same prompt, if they want.
3. If you post a request, try to fill one too. We don't want this to be all prompts and no responses.
4. While anonymity is encouraged, if you decide to de-anon you won't get flogged for it.
5. Crossovers are allowed.
And here's a long list of kinks for inspiration: http://eliade.livejournal.com/472331.html
