Sherlock fans - any recs?

Hi - someone on my flist who writes LOST is wondering about LJ sites where she might post her first Sherlock fic. I don't know much about that fandom on LJ - and I take it she's not on AO3. Anyone have a link or three to active Sherlock sites on LJ that might be welcoming to a newbie? What I've read of her LOST is quite good, I expect her Sherlock will be, too.
