She should draw up a list. Although I think you can get exemptions if your own imagination produces sufficiently weird stuff, like squidfic and carpreg.

I haven't done it, because I'm in the middle of the steampunk AU, the Richard-turns-into-a-car-and-they-all-shag fic, the nesting box fic (because I haven't invented enough weird Top-Gear-Slash specific genres), the Might Boosh crossover, the Richard/Oliver/Zonda love triangle, the Torchwood crossover, and haven't even started the Big Gay Wine and Cars Challenge (Jeremy and Richard v. James and Oz in a contest of drinking, driving, and rampant homosexuality).

So, er, yeah. Me 'splode soon.
