Re: your list. Well yes, some of the topics could be smushed together if you wanted to shorten it (for instance, you could include Vampires, Werewolves, and Elves under a Supernatural Beings umbrella) but why bother? If I were setting up tags for my Pinboard list, I'd want to be as specific as possible. But that's me.

Just looking at it quickly, maybe think about adding College or University AU (since you already have High School AU), hurt/comfort, other creatures (like clones/zombies, etc.), and cross-dressing (when I set up that cross-dressing list for popsoundboard I found over 60 stories!).
