I think it's a great fun idea but with shipping costs, this board being so global, it would be crazy expensive. They recently raised the rates in the US and made customs forms even more difficult. If somebody agrees to be in it, it might cost $10 in supplies but $60 in shipping for multiple packets.
What I would love to see is straight trade
