Well I am glad you weren't turned away, as you have obviously contributed much to this forum.  As I see it, though, the nexus should not be "a place for everyone to hang out."  Hanging out suggests a certain amount of stagnation, IMO, something that could become the downfall of this community.

The nursery requires a certain amount of humility in new members.  The price for full membership is an open mind and a willingness to learn.  I do not think that is too much to ask.  Yes, certain subforums are "private", but it is hardly a feat to get promoted.
