I have no idea if this has been brought up before or not so...
I really think there should be a rule that you have your full name/email address in your post when you put something on the classified board. With so many scammers out there these days, I know most of us are much more wary of buying from anyone without basic info. I know that you can always PM a person, but I think making this mandatory would be an asset to BP net, especially with as many new people are joining this board on a daily basis.
