If you have a twitter.com account, you can integrate it with Postcrossing. When you send or receive a postcard, Postcrossing will automatically publish that to your twitter.

Here are some samples:

• Writing a #postcrossing postcard to Brazil
• Received a #postcrossing postcard from Russia - http://tinyurl.com/6huxtl
• Received my first postcard from www.postcrossing.com - http://tinyurl.com/67xpej

To activate this, you just need to edit your account and connect it with your Twitter account - you will be taken to twitter.com to approve the connection between the two accounts. You can at any moment disable this functionality.

If you don't have a twitter account and want to learn more about this service, visit twitter.com website.
