Small plots, I think. One or two other people per plot. I will do more than one so please pitch more ideas, even if there is another plot happening.
A bit leary of doing this because I'm only on book four, but ah well.
I have one small plot idea, wouldn't work with a huge group though.
My idea isn't much of a "plot," mainly a characters. The story with an Aes Sedai and her Warder would be great. Romantic or not, I have no preference (would effect Ajah though, so we'd have to decide right off the bat.)
I don't mind worldbuilding spoilers for the book, just not plot spoilers.
