How about an automatic pop-up whenever someone starts a thread in buy/sell section?
Problem is, Peetza, there will ALWAYS be some way for a member to "not see it" or "didn't receive enough help". No matter how much effort we put forth to make things as simple and smooth as possible, it will never be enough to satisfy everyone. So, we have to draw the line somewhere.
By the way, that was a very good suggestion...
