I know that you have a system in place where certain "area's" open up after someone has 50 posts. And I understand the logic behind this....so that the casual observer cannot get into these area's. However, I think the flaw is that many people put up stupid posts like "Yeah I like that trick" just to get their counts up to 50. To me, this creates clutter.
My suggestion is that in order to have access to these special area's, you must be "approved" by 2 other members of the magic Café. 2 members must submit their approval or "sign-off" that you are legit and know what you are talking about. Then, and only then, would you get access.
Just my two cents.
