Fantastic. I truly think this is one of my best discoveries on the net. I also had a repayment today - yes, just a small sum, and it will take a while to come back, but it's monitored.
We make a loan to Filipino entrepeneurs with each holiday booked. I know it's not the same as giving, but it's a great device for getting that money to the recipients. We aren't guaranteed to be repaid, but the percentage is high. To me it's a positive thing we're doing in our currently limited way which will (unashamedly) reflect well on us, in the same way as we look to encourage eco-tours etc.
I'm not a philanthropist, and can't see that I ever will be, but Kiva is a scheme that really delivers.
