I recently got ripped of by a dishonest member of the hamb. This was my 1st bad experience; I have bought many..many parts from honest people on the hamb trying to help fellow enthusiasts out. I would like to post his name (to warn other people not to buy from him) but i would like to go through the proper channel. i'm sure there are instructions somewhere how to go about it...but i cant find it. what do i do?
