Dang, sorry this is such a late reply. I only get on this page when I have something to post.
The meet-ups tend to have a lot of guys, but there are at least two female members that have been in the group for a long time (Christi Chan being one). They tend to miss meetups due to other commitments. At the last few meetups I attended though, there was at least one lady showing up for the first time at each meetup. But first timers sometimes don't come back.
We'd certainly like a more balanced gender representation, as the group is open to everyone.
