Do you know Postcrossing?

Postcrossing is a great way to practise English (and other languages too) through postcards... Do you know it?

Last year, I suggested my students to join Postcrossing project... What is it? You write a postcard to someone, and someone will write a postcard to you. It is like a chain of postcards... you send one, you get one. Always a surprise, always a smile!
