Crisis in Darfur - Want to help?

So, I saw an interview with Don Cheadle (the actor that played the hotel owner in Rwanda that harbored people during the genocide in Hotel Rwanda) where he discussed his involvement in a movement to bring awareness to the plight of the people of Darfur in the Sudan. This interview prompted me to do a little research. Here is the website he was promoting Not On Our Watch Project. The project is in conjunction with the International Rescue Committtee. I also found a comprehensive NPR story, which also has excerpts from the book of the same name. It's all very sad and compelling.
