Nicholas Kristof the Pulitzer-Prize winning columnist at the New York Times (and confirmed speaker at the 2007 ideaFestival) has been relentless in his on-the-ground reporting on the horrendous situation in Darfur and in pushing for an end to the violence there. Now he is inviting others to offer their "practical ideas" for Darfur. Suggestions can be sent to him at DarfurSuggestions@gmail.com.
