More that I'll admit I have been screwed by an ODT'r , usually newbies, but not always, because I, thinking I'm being courteous listing my name & phone in a PM, basically to ask or answer questions. So to leave an avenue open to leave a negative feedback to a really deserving party, insist all agreements, meeting places and times be via PM, even if yo do it via phone, insist on a PM confirming whatever you discussed/agreed to. Never talk a Man you don't know really well by his word or you'll wind up with pie in your face and be pissed with no recourse.
