We did some #Postcrossing this weekend, finally. Weeeee!
Maria Langer | 📝🛥️💎@User47 Who do you exchange postcards with?
@mlanger folks all over the world. The service gives you an address and a number. When the recipient registers it, then someone else gets your address. It’s pretty sweet
@User47 How do I get started? I love the idea of sending receiving postcards.
@mlanger I wrote about it for AR back in the day. I just did a re-read and it’s still all valid if you are interested in a primer from a fellow traveler’s perspective
