A good question...
There is also a usergroup called Ask a Woman.
I think the decision at least at this point, should be left up to the women. Understandably, they may wish to see how things go with this section and how the rules will be applied before they give up on the usergroup where they have more control, or the thread which is easily ignored.
Edit: It may be worthwhile adding a poll (non-private so we know that the votes are actually women!) to the thread to find out how they feel about it.
