The registration for Postcard Geography is open until Sept. 18th. This is a postcard exchange open to classes and homeschoolers. There are different age groups that you can sign up for. You can mail postcards, or send e-cards. My boys did this last year and loved it. Last year there were about 200 classes from the US and a few from other countries that signed up. http://pcg.cyberbee.com/ Amelie
