The idea of a remix is that each participant is assigned a writer and you rewrite one of her or his stories. From the rules:
In rewriting, the participant can change any stylistic element they like - point of view, structure, mood, length, language style... just about anything. What they can't change is the fundamental story. What would be the point, otherwise? The basic events, people, and times of the story must stay the same.
You're also allowed to designate one of your own stories as "off limits" to remixing if you want to, and when you sign up you can tell the mod what you absolutely won't write, whether it's a pairing or a character or whatever.
Check out the community to see previous remixes, which are all linked to the story which inspired them. Note that
