You can claim anything you want, be it het, slash or gen. You can even claim Threesomes. Any character (be it on their own or in the pairing) claimed needs to be in the story either direct or through someone thinking of them/having an effect on someone.
Additionally, you can claim as many tables as you want and different people can claim the same table with the same pairing/character.
Stories
Stories should be at least 200 words long with no maximum limit. All Ratings are fine. There is no timelimit to finish the table.
Use one prompt per story. If you want to write a whole story with a table, you can consider doing so by making it a series with seperate ficlets that still rely on the others for knowledge.
Since the minimum is 200 words each story used for the prompts should be completely new.
Additionally, please tag your posts with fandom, pairing/character claimed and your username. I'll try to create tags as you claim so they're available. Should there be any problems with tagging, just comment here and I'll take a look. I'll try to use memories as well, but since I haven't used that function before I can't promise anything.
