I made a similar inqury on C & D. There are a few females there, but they like to keep it quiet because of:
A) getting "hit" on once their identity is discovered
B) they tend to get discredited once their gender is revealed.
I disagree with both aspects. There is a girl at C & D (Racert) that knows her stuff. She is very impressive. There are a couple others there too, but they don't post very often.
Welcome ladies, you have my respect.
