On the topic of attempting to get more women, then good luck. What I tried to say and I left it out and went off on a tangent is that PHP community is trying to do this as well for the PHP engine as well. There are many women who are programmers and only so many of them. Majority of programmers are men, just how it is. Read what the PHP Engine developers and community has to say about this and try to get involved with them first and see how they were able to succeed or why the failed (as a guy, a female only zone is something I respect and dutifully ignore completely as it has nothing to do with me, as a man).

I don't see it as the male programmers being biased or insulting towards female programmers. In fact, I would be happy to see more of them, because they are such a rarity. I think that when you have them, they either feel as if they shouldn't tell anyone they are female because of the harassment from male programmers at the novelty (who damn near ruin it for the rest of us) or because of the feeling that they might be required to "prove" themselves to their male counterparts.

That and the real world effects it as well. Women are still expected to hold the fort and is referenced by a few (well, accurately only one woman in the PHP community) of the women in the amount of time they have available to contribute to any community.

Again I went off on a tangent. There is already a movement in the PHP core community that can be drawn from in order for research and having an example for how to start. Learning from those that have already tried is a good way to start. All I have to say is that I wouldn't mind seeing more female programmers in a completely creepy way if you will, but not that creepy.
