So you have this cool stickers from you local hacker space or your favorite open source project and want to spread them all over the world? Or you are searching stickers of your favorite thing? For this we have build our newest feature: Swap! Here you can swap your stickers with other hackers, makers, geeks and nerds from all over the world. Just submit your sticker to our swap area, we will publish it after a short review (just to make sure nobody is trying to trade things here) and you will get an email with a link where you can modify your offer if needed.
If you see a sticker you like you can just write a request to the offerer and she can decide if she wants to get in touch in you. If so you both will get an email in CC and now you can negotiate directly.
