Hi - Have you looked into a website called
www.postcrossing.com? I recently joined, and it is a rather nifty way to get stamps & postcards from around the world for the price of a card and a stamp. How it works is you request a random address. The system gives you one along with an ID# that you write on the card. Once the card arrives, the recipient registers the card on the website, and now YOU will receive a card from a random user. This is a worldwide group.
