I had one recently that reminded me of high school dating. I listed an item for sail/trade and the member posted "call me". I pm'd him and wrote "pm me if you want to make an offer". He pm'd and wrote "call me if you want to sail/sell". I did not.I love these PMs: "Hey, send me a text at 7704910061 so we can make a deal." LOL.
(actually made some good trades with these folks once we set everything in a PM)
