While looking at items that have been for sale lately,I can't help but notice that many of the sellers have ten or fewer posts. Another firearms forum that I belong to doesn't allow selling without at least fifty posts. Has anything like that ever been tried on QRZ? It seems like this is a good way to discourage disreputable sellers. It also seems like a good way to encourage even more participation. However, conversely it could lead to posting just to bring up your post count.
