Oh gosh, I don't know! It's always a bit easier with the popular and well known ones bc more people are likely to respond? Star Wars, Star Trek, MCU, Super-Who-Lock/Elementary/other Holmes variations, Harry Potter, ASOFAI, CW's DC verse, mythology, fairy tales, LOTR/Hobbit/Sil, Wonder Woman, Buffy. Just because I write in it a lot, I always like Narnia but it's pretty obscure. I know that in some years, there's stuff posted that I don't even know what it is - -video games and anime and other things. It's lovely and wide open. Oh and it would be a great treat to see anthropomorphic fic too! I'll post some prompts to get it going tomorrow.
