i think a trade dispute forum is a great idea, i personally would put it in the restricted age section, and if not solved then have it moved to the general.
id like to say we should have volenteers to help out with long distant trade diputes. stocko is currently doing this for me. im not saying a lynching party, but a group of guys in major areas willing to go to the homes of the accused and sort things out face to face.
its easy to ignore a pm, not so easy to ignore people at your door!
