The first step is to request to send a postcard. The website will display (and send you an email) with the address of another member and a Postcard ID (e.g.: US-786). You then mail a postcard to that member.
The member receives the postcard and registers it using the Postcard ID that is on the postcard. At this point, you are eligible to receive a postcard from another user. You are now in line for the next person that requests to send a postcard. Where the postcard comes from is a surprise!
You can have up to 5 postcards traveling at any single time. Every time one of the postcards you send is registered, you can request another address. The number of postcards allowed to travel at any single time goes up the more postcards you send!
