advanced forum access is not a right. Nor is the advanced area some secret club, its just an area that more sensitive information is discussed, no more and no less.
Many in the past have had up to 1000 posts and been denied access, posts dont guarantee entry, ie posts of lol , and smileys will not be counted, when a mod reviews a members posts, they look for attitudes, helpfullness, contribution and post content, all decisions are based upon this alone.
to ask mods to email everyone declined, is not workable, as to email 50 times then deal with the 250 follow up emails a month would be a full time job for someone.
The system works and is as fair as it can be, congrats to DB for easing the plight and producing a system that works.
