I started the program a few months ago and I'd have a lot more postcards if I weren't so lazy. :3 For every postcard you send/is received from you, you get one from a random place in the world! I love to hear about all the different places people are living their lives and to see tidbits of their world photographed and printed on a cute little card. Plus, who doesn't like snail mail, amirite?
