Want to be one of Santa's elves?

About this time each year, the US Postal Service prepares to start mailing letters to the North Pole. Now they have launched an online service that allows users to "adopt" children's letters to Santa, in order to help deliver gifts to low-income families.

The USPS Operation Santa website has been publishing photos of Christmas wishes from children in 15 US cities where parents may not be able to afford many gifts. Users can volunteer to anonymously fulfill the Christmas wish on behalf of Santa. To help Santa in this way, create an account on the Operation Santa website; select a letter that touches your heart; fulfill the Christmas wish as desired, and ship it from a participating post office before Dec. 21. Children in cities listed on the website who want to send a letter to Santa can address it to Santa Claus, 123 Elf Road, North Pole 88888.
