Hey, I just recreated a couple of my comms from LJ over here and thought I'd pimp them a little bit.

spn_random is a writing challenge comm for Supernatural/Crossover pairings. You choose a character from Supernatural and another character from any other fandom of your choice and write fic based on a set of prompts.

spn_roadside is a writing challenge comm, again for Supernatural, where the author writes fic for prompts based on roadside attractions, historical landmarks, or other things of that nature.

and finally,

fairytale_redux is a multi-fandom challenge community where either an author or artist choose a Brother's Grimm fairytale to rewrite for a fandom of their choosing.

Everyone is welcome to participate, so stop by and check it out!

Here's the first post. If I've missed your comm and you want to be here, please let me know. Just comment here! ^^; As long as it's a themed or weekly challenge community (not necessarily inspired by 30_kisses, fanfic100, or wednesday100), I'll probably archive it.
