On Kiva, you can join groups. The number of projects funded is indicated on your profile. You get 25$ for each referree.

Your lend comes back at the term of the project. Then you can reinject it into another loan.

Finally you help more people comparing to a simple donation.

Of course, some causes still need donation, like international handicap, action against the hunger.
