Santa Claus is going online. The Postal Service has launched Operation Santa and for the first time is taking it nationwide through the Internet. The program matches sponsors with children in need who write letters to the North Pole. Some ask for gifts, but some ask for help with other issues. Businesses and nonprofits can adopt a letter to see if there’s something they can do to help. Children can send their letters to Santa by mailing 123 Elf Road at the North Pole. Zip code is 88888.
