From here, the best we can do is donate money to the organizations that can best get to the areas that need the most help and supplies.
I personally chose to donate to Doctors Without Borders, which narrowly edged out the International Red Cross. I think either of these are worthy.
If nothing else, my donation makes me feel a little less helpless right now.
Updated: You can now donate to the American Red Cross (earmarked for Tsunami relief) via Amazon.com (http://www.amazon.com/paypage/PX3BEL97U9A4I)
