It became three in each place where I'm active(ish).

In order, these are a community where all types of BBC Sherlock content is welcome (you can post fic, art, links, meta, etc), a prompt meme for BBC Sherlock, and a fanwork rec community for all types of Holmesanian works. They have one thing in common: their LJ-sisters/clones/originals were all a huge part of my very earliest fandom experience. I love them a lot because of nostalgia and how much they have meant to me.

They are not as active as they once were (and I admit that I've done very little to help out here) but hopefully they can become more active again if more people start using DW again. I'm hopeful!

Tumblr
femslashrevolution -- a multifandom femslash blog that's fighting the good fight and is very active even after female presenting nipples were banned
Rejected Princesses -- artist and writer who draws comics (and publishes books) about forgotten women in history
Salt of the AO3 -- the wailing wall of fanfic writing

Pillowfort

Full disclosure, I have no idea how communities work on PFIO yet, but have some anyway! Since I don't quite know how they work, I can't really say if they are good or bad either, but I'm putting them here in hopes of finding more people over there!

SherlockLadyLove -- for those BBC Sherlock fans who like femslash and support the female characters in general
221B_Baker_St -- an Holmesainian community
Kingsman -- a Kingsman comminuty

...I really butchered the formatting on this one.
