This is an interesting thread :)
I myself have used Linux since 2002; but I have yet to find an organization or a means to connect with other women with similar interests. The thing is, I am not a programmer and I do not work in IT (I'm a simple bookkeeper, trying to "move up" to be an accountant). I'm slightly "tech-savvy" in that I have an Associates degree in electronics technology...but I've moved away from that.
I used to be involved in a LUG in Florida that was sort of fun because it was very large and I found a small core group to talk with. However, I'm not too motivate to join the LUG up here in Pennsylvania because it's based at a university and I don't know if I'll be able to really connect with them. Again, I'm approaching Linux from an end-user standpoint; and I'm mostly interested in the deployment of various open-source programs...not the development of them. I'm especially interested in open-source web design & management programs.
I think the Mac community has more resources available for women; hopefully Linux will get there one day! :)
