I've been wanting a multi-fandom fanfic finder comm for ages (I have so many fics I want to find in older/more obscure fandoms, it isn't even funny), but none ever popped up, so I finally broke down and created one myself:

fanficfinder

You can both look for fics on this comm and request recs.  Currently the comm is still being tweaked, so suggestions are greatly appreciated.

See you there!
