John,
I think the forums are good as is, sticking with greek-related issues. Seems like when other topics (such as sex, or relationships) is relevant, it's brought up anyway...and no one's shy about sharing!
One new heading I would like to see is a forum for GLOs that are larger than a local, yet are still growing into a national GLO.
From personal experience, there are a lot of issues that affect such GLOs, that most established and flourishing GLOs have already dealt with (in most cases, 50 or more years ago).
Some examples: maintaining uniformity between chapters, making the transition from a colony to a chapters, the logistics of expansion, the fluidity of chapter "traditions", making the decision whether or not to affiliate with an already established GLO....I could go on and on.
