There's a Women Love Fest going on over at
womenlovefest.
Initially begun to celebrate the women that fandom hates, it's more generally turned into a women love-fest, simply because every female character in the history of fandom has been run down by someone who thinks she shouldn't have kissed/smiled/spoken to/stood beside a male character, or dressed like a slut/whore/woman who's comfortable in her own skin, or done something good/something clever/something morally questionable/anything at all.
So far, I've found threads for Teyla, Jennifer, and Elizabeth in
Stargate Atlantis; Sam and Vala in
Stargate SG1; Helen, Ashley, and Kate in
Sanctuary; Olivia and Altlivia in
Fringe; Morgana and Gwen from
Merlin; and Ziva from
NCIS - to name a bunch of my most popular fandoms - but there are plenty more fandoms and plenty more threads!
I know the majority of my f-list love the female characters, so I think this counts as 'relevant to our interests'.
