Like many others, I had been trying to figure out how to ensure that any money I donate for Tsunami goes to a good organization, with a low overhead. My brother who works for GE, told me how their company is doing matching contributions. Moreover, they have identified several worthy organizations doing relief work on the ground, and are directly giving the money to these organizations.
I ended up making my contribution through my brother. If you are thinking of making a contribution, then look for a friend/relative at a company doing matching contributions. Its an easy way to double your contribution.
