Postcrossing

What is Postcrossing? It is an online project allowing people to send and receive postcards from all over the world. The name is combined from two English words – “postcard” and “crossing”. The first step is to request an address of one random member and a postcard ID on the site. After the postcard is received by that member, then she would register the postcard by inputting the postcard ID. And the system would confirm that you have successfully sent a postcard to the others. At this time, you will be picked randomly by others and others will send you a postcard. That means “send one, get one back”.
