What does the term "bump" refer to? Dumb question but I don't get it. What about other terms n such? I'm a pretty new user on MP especially when interactin in forums. Any advice on etiquette and tips for what to look out for on the For Sale dirtbag climber exchange? I am interested in buying and trading but thought I would get some advice from more experienced users before I get too carried away;) I sent a payment thru PayPal for a cam and it's been since last night and I have not gotten a response on the status of my "order" or payment receipt notification from seller. Maybe he's out climbing;) just a bit wary but trust that most of the folks on here are legit.
