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 enter your twitter username and password - don't forget to check the "Publish to my twitter account" option. 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.
