This is a really interesting concept. Simply type up a letter online (up to 800 characters), enter a destination address, and they'll post your snail-mail letter free of charge to any country on their letter map. Make sure you use a real email address (or 10-minute mail) as you'll need to respond to a confirmation email.
Letters are handwritten and posted by volunteers who are participating in this experiment. You can become a volunteer yourself and write snail mail for other people as well.
I can only imagine some of the interesting uses people will come up with. Please share in the comments section.
Time for some fun. Enjoy :)
snail mail spam has become a reality?
