Today's challenge is a pretty simple one. Vote to donate! Take Part and American Express have created something called the Members Project. If you go to that link, and create an account (it's really quick!) you can vote once every couple days for a charity that you want to receive a donation from American Express. There are several different charities under different categories like Health and Environment. I cast my vote for the American Cancer Society!
Another great thing about this site is, if you have an American Express card, you can donate your membership rewards points. The site also helps you find volunteer opportunities and it has "Take Action"s, which are quick ways you can give back! So be sure to cast your vote! :)
