Fanfiction Classification

[Reisheiruhime]

Ok, so, here's the deal. I've got plot bunnies running rampant, and I don't know what they should be classified as.

There are several elements to these bunnies. The Amnion, the Yautja (Predator, etc...), Stargate (SG-1 and Atlantis) stuff, and a few original characters are all hopping around in my head. Now, the question is, What catagories do they go in???

Oh, bother, more Harry Potter nonsense. Thought I told you to leave.

So, erm, should it just rely on which setting they're in most, or what? Heeeeelp....
