http://lists.wikimedia.org/pipermail/gendergap/2013-May/thread.html shows me that "Topless image retention -don't give up" has stretched on pretty long, and it seems to me like it might be better suited to onwiki discussion instead. Maybe the posters who are very interested in engaging in that conversation could hash this out on Commons or Meta and send this list an update when you have a solid proposal or conclusion?
A few things I'd love to see more of on the gendergap list: sharing useful or inspiring blog posts and best practice documentation, promoting the School of Open's Wikipedia-editing course https://blog.wikimedia.org/2013/05/10/school-of-open-offers-free-wikipedia-c... and similar courses to women, and learning from case studies of Wikimedia projects (or other free culture/free software communities) that have improved gender equity.
