I belong to a women's industry group and pay dues, in a very gender-unbalanced industry. We talk about issues that are very specific to women: how to get more of us in the industry, mostly. Men of the industry are always welcome to our social events and I think they enjoy coming along because it's the only place in their own work lives where they get to hang out with women. So we're showing men what a world with women in it, is like. Eventually we won't need the industry group, once we're well-established.
