I didn't intend to get off-topic. I do get confused these daze.
I understand your points and respect your opinion. I just don't like the whole world seeing my full name in open forum because ID theft is far too common. Anyway... anyone who sends payment will know who the seller is by full legal name and their physical address... or at least their PO Box. I don't see how using one's full legal name in open forum will help. Adding to that... who's to say a seller won't post under a false ID? And if payment is made through PayPal to an email address then the buyer still doesn't know if the seller is posting under a false name. I just don't see how any of that will help prevent abuse.
