I have heard about "sending stuff" in regards to this and other catastrophies, that money was best. China "generously" offered $100,000. For them, it it not even pocket change. It is the coin in the parking lot that you don't even bend over to pick up. Stephen Colbert (Colbert Nation) suggested to "beat" them by donating ten dollars at a time by texting COLBERT to 50555. So far, they are up to $85,000. (Do you think China will be embarrassed?)
But other very worthy organizations have been mentioned here, also. I think the key is just caring and sending money however we, the privileged and safe choose to do it.
