Once you sign up and send a post card, Postcrossing tracks your cards- above is my map
(I've only sent one so far but some postcrossers have sent thousands!). I got an address and a
little information about the person who would receive my post card plus a code to track it.
Here is the a.favorite design postcard I sent off to Rosrath, Germany.
Postcrosser event held in Baia Mare, Romania. They hung 400 postcards in the
local post office received by postcrossers. See more about this event here.
Check out the Postcrossing Facebook page. Postcrossers from all over have been posting pictures of their favorite mail boxes. I love this one at the Vatican posted by Herald Ket- see post here.
