Good luck.....he has 111 posts......all this month. In very random forums. Ive sniffed out scammers before and this is their exact MO. Did he ask for tracking info with payment?
I was going to agree that 111 posts is pretty light to do business with and then I looked at my own post total.
I think join date is more important that the number of posts. I for one lurk a lot, just do not post much.
