First lady Michelle Obama is already getting ready for the president's birthday next week, when he turns the big 4-9. She sent out a mass e-mail to supporters Tuesday asking them to sign Barack Obama's birthday card on the Organizing for America Web site, where users must enter their names, e-mails and ZIP codes.

"Every year, our family tries to come up with a fun way to wish Barack a happy birthday," she wrote. "Together with other Organizing for America supporters -- and me, Malia, Sasha and Bo -- we'll wish him a happy birthday and let him know that we're ready to take on the year ahead alongside him."

Organizing for America's spokeswoman did not respond to a request for comment on whether the information would be used for fundraising or added to OFA's already massive e-mail list.
