There is a new comm called dcu_femslash. It's exactly what the name says ... a community for femmeslash pairings in the DCU world. All incarnations are allowed, which includes SV! So if you want to write some Chloe/Lana or Lois/Kara or Lois/Tess, you can totally post it there.
I thought it was quite cool. If you think so too, go join! :D
