The Spook Me Multi-Fandom Ficathon is open for sign-ups through this coming Saturday, September 15th. You can sign-up here.
This is a multi-fandom challenge, but I think it's quite appropriate for Buffy fandom. It's a fun, low-pressure challenge, and if horror isn't your bag, non-spooky stories are gladly accepted.
There are a lot of creature prompts to choose from, including Aliens, Boogeymen, Spiders, Mad Scientists, Cyborgs, Dinosaurs, Men in Black, Maniacs, Shapeshifters...it's a long list, and widely varied. So come on over and join us at spook_me.
