I joined
Postcrossing a month ago, and I am delighted with the idea of having sent 10 postcards (4 of them are travelling to their destinations) and having got 6 postcards to and from all over the world.
Postcrossing is amazing: you send one postcard, you get one postcard. That's it. And opening the mailbox, usually full with bills and other unpleasant envelopes, and changing that into a postcard from any Postcrosser, is lovely. In addition to this, most of Postcrossers know English, so it is a great opportunity to practise it.
I recommend you all to join this community. You only need to have an email account, money for postcards and stamps, and to feel like doing it.
Once you have got your first surprise postcard, you will get caught ;)
