I thought PAX seemed like a perfect opportunity for a boardgame trade meetup. So I've set up an auction list
on BGG for anyone who wants to get involved. You can put up games from your collection, expansions, promos, etc. And hopefully find some gems that you would like to have.
This is a bit of an experiment, so feel free to ask questions and give feedback. And please share with your friends - the more people who are involved, the more successful the event will be for all of us.
