Do you have any advice for fan fiction writers?

I mean, this is early enough in this process that I think it's kind of the fun thing, where not everything is so locked down. It's not such an established world like Star Wars or whatever, where there's become a very rigid set of rules. It's fun to just see. I've been going on the fan fiction section of the forums and reading some of the stuff. A lot of it's just fun because people are using their imagination and imagining where they would like to see the universe. And that stuff is just always great to read.
