The fee thing is an interesting idea but I don't know how that would work in reality. Food for thought though... I've run a few forums it works well when you need real access restriction or age verification. I would think most active posters in the CE forum would pony up the $2, but those who like to cause trouble could easily be banned since they couldn't repeatedly pay for new IDs. Honestly though this is a pretty tame group as most communities go... one of the most laid back I've seen actually.
