So, you may or may not be familiar with the concept of Postcrossing. The idea there is that you register as a user, and you'll be sent the mailing address of another registered Postcrossing user. You then send that person a postcard from your local area, over the traditional postal system, so that they can get something that relates to the country you live in. Typically, the mailing address you'll have to send to will be overseas to you.
