You might have noticed we are already in countdown mode for the postcard number 4 million in Postcrossing. That's right, 4,000,000 postcards! Can you believe it?! (we're still having some trouble wrapping our heads around that number ourselves...)

For those of you who've joined Postcrossing recently, you might want to know that Postcrossing reached the first million of received postcards in April 2008 - that was only 3 years after its very start. That date made us immensely proud of Postcrossing and of all our members. What we didn't know back then was that it was only the beginning!

In February 2009 - less than a year later - we reached the 2 million and by September we were already celebrating the 3rd. And now, 6 months later, we are preparing for the postcard 4 million!

We like to celebrate these milestones with all Postcrossers and so, continuing in what has become a Postcrossing tradition, ladies and gentlemen, we're pleased to announce the forth edition of the "Guess the Countries" contest!

All you need to do is to leave a comment on this post with your guess about which country the postcard 4 million will be sent from, and where it will go to (example: From Tanzania to Iceland). It's really simple! The first to guess it correctly will be declared the winner, but only one guess per person is allowed! We will announce the details of the lucky postcard when it gets registered.

But... if there are winners, there must be prizes, right? I'm glad you asked, because there are awesome prizes for both the correct guesser and the sender and receiver of the lucky postcards!

Our friends at MOO (makers of all things printed and pretty) have agreed to partner with Postcrossing and offer 3 packs of 60 postcards for the winners!! How great is that?

With MOO, every single postcard you print can be different, and have your own pictures in it. If you're not a keen photographer, don't worry! They have an incredible selection of ready-made packs that you can choose from.

Also, until April 15th, MOO is offering all postcrossers a 15% discount on the purchase of any pack of postcards (20 or 60), with the code POSTCROSSING15. Aren't they sweet?

So, take a guess in the comments, and write/register lots of postcards. Let's get the party started! :)
