I'm on several other message board and most require a minimum post count ( usually 50 ) and moderator authorization before a new member can post in the trade forum. This help keeps ppl from joing and using the forum as a free eBay. Just a though.
At the same time we don't want people to spam the forum just to be able to trade either. If they are a newer member you are weighing out your own options and hopefully all trades will work out just fine.
