If you're looking for a charity to donate to, an excellent place to start is
http://www.networkforgood.org/
There are links to make donations to other relief organizations as well as the Red Cross, and links for volonteer organizations as well. What I like about Network for Good is that these charities have all been checked out and are legitimate. Amazon.com also has a link to allow you to donate to the Red Cross using your Amazon.com account - some other e-tailers have similar setups, so you don't have to enter your credit card number into an unfamiliar web site.
