Micro. We all got together on one big trade. You make as many stickers as possible. I dont know what the goal was last time, but i made near 100. And we sebd them to the one person in charge of the trade. This time it will be me, last time it was bob. You should also send a few bucks, or a stamped envelop, and we split up all the stickers, and mail em back to you. Then make sure t get good pictures of all the stuff you put up for everybody, and hope they do it in return. It's a nice deal, and a good way to get your word out all over.
