I think a large segment of Buffyverse fandom has heard the news thanks to Petzi and the Herald (and I'm planning on posting at whedonverse_nb), but I'm hoping to spread the word across as many fandoms possible.
What communities would be good avenues for pimpin'? I want to encourage interest pan fandom. Please post comments with suggestions!
Other ways you can help (if you feel so inspired!):
+ post a PIMP banner in your journal (banners here, instructions here)
+ leave PROMPTs
+ WRITE stories
+ read and REVIEW stories (fiction masterlist here)
Remember this is flashfic--it's very low pressure and it's a great opportunity to experiment with writing. I know some people who started writing for the first time and others who try writing for new fandoms. Basically, everyone come out and play!
