Hey Marlin,
I haven't bought or sold anything on the trading post, but 100 posts is not an unreasonable number to do this. It would keep the bad guys out and would keep the good newbies in. also it would give the new folks an idea what this forum is all about. Plus I'm sure it would help the mods.
I don't want to piss off the buyers and sellers ,but I think it would weed out the assholes. Just my .02.
