Yes I understand where the 7000 number comes from. The number of active users which most vbulletin boards display by default has been removed on this site - no doubt the reason why is because it is far far less than the 7000
Anyway so the number is? You aren't being very transparent here ... how many active users does GPWA have? I could post a number, but I would rather give you the chance to be transparent since you have stated that the GPWA wishes to be just that.
After that we can get onto how transparency goes hand in foot with having most of the site being private.....
