Ok, a question:
Who out there has a group or has had a group that was mostly women?
Or one where a woman was the GM?
And what systems did you play?
I know there's me, (mostly women, many days all the players but me are women, and Satine GMs at the comic store about once or twice a week) and there's Dungeon Mistress. There's also some LARPers I know and I know the women on All Games Considered often GM...
And what we play is a matter of public record (for us: mostly old school mostly D&D, though Satine runs 4e. Dungeon Mistress played I think 2e.)
Also, to make up for the lack of content in this post, I've added a bunch of pictures to this post, including Mark Twain being serious about his game and Edward Gorey sitting next to a teddy bear...
