(only it doesn't have to be anonymous)
The rules are simple. You comment here with your username, and people can tell you what they want to see you write. Or draw, or vid, or icon, whatever. Despite the name, they don't have to do it anonymously, though of course they certainly can. You then go through the comments and if you see that person who you've always wanted to write a Green Arrow AU set in the Terror, where Ollie is a Scarlet Pimpernel-esque figure, smuggling people out of Paris, then you tell them that they should write it.
I'm here. Nothing's guaranteed, this is more of me saying "I'm open for bunnies."
Especially ones that I might be able to stretch out for 20,000 words possibly.
