Trading via mail is great, but I much prefer in person exchanges. I've been pondering what a trading event might look like, and thought i'd start a discussion to see if we can come up with some good event formats and guidelines.
I'm not sure jumping right into an event where trading is the only activity would be the best, I feel like we need to let Pinny Arcade mature a few more years first. However combining pin trading with a game night seems like an excellent idea. In fact it might be a perfect fit. There is always down time as one game finishes, and you wait around a bit until some other games finish and you can mix up the crowd and play something new. Now the people not playing could bust out their lanyards/boxes/binders at an empty table and begin the trades.
Eventually, actual Pin Trading events seem likely, but what might they look like. A hall could be rented and you could charge admission. But a better way might be to encourage big volume traders to pay a small fee (to cover hall rental, etc) for their own table where they can spread out their wares, and invite any and all with no cover charge to come trade with those at the tables and each other. This is how many swap meets operate.
Personally I've never gotten into the Disney Pin Trading, anyone into that and have experience with meet ups (trade ups?) from that world that we can learn from?
