I received the following information about what seems to be a good cause and I thought I'd share it. Note: I have no personal knowledge of this organization so be sure to do thorough research before donating to it if you so choose.
My organization, International Medical Corps, has the ability to save the lives of malnourished children around the world and we just received some very exciting news. We have been nominated to be one of the Top 25 in American Express' Projects, "Saving the Lives of Malnourished Children." Our project was chosen out of 1,190 projects and is now eligible to receive up to $1.5 million to help feed hungry children. Because your blog, Christifideles, has a loyal following, I thought this would be an issue you would want to share with your readers. I've put together this microsite explaining everything.
I've confirmed their claim here.
