Also need to know what that minimum post count is. On my CRN we have a 50 post minimum before newbies get an button, but usually let people post stuff for sale after at least 10 posts, otherwise frowned upon. We don't have a set rule though. Just keep an eye on anything suspicious. Overall has worked fine, it's not like a national GIANT forum with tons of unwanted people or vendors. Doesn't even seem necessary here unless it's being abused.
But then again I was off MASC for a few days, only to return and find a half dozen closed threads, drama, and other b.s., lol. So maybe I don't know what's happened lately.
