So far I've swapped by shipping once (we both shipped simultaneously) and purchased from other forum members via shipping (they shipped after the money was sent) a couple times. Every experience has been perfectly smooth, though in 2 of 3 of my cases it helped that it was with someone I'd had numerous exchanges with in the forum. In the 3rd case it was with someone who was a lurker but not much of a participator. It all felt above board to me and ultimately it was. Still, probably a good idea to send funds via a method you have at least some potential recourse from, like using a credit card via Paypal (which is what I did). Doesn't guarantee any protection but, it's better than nothing on the off chance something goes sideways.
