This site is to raise money for the Rainbow Orphanage in Watamu, Kenya. I spent 10 days there over Christmas 2011 and had a great time, and was impressed by what they do:

I wrote about it here (also lots of pics):

Yes, I know this website is pretty lousy
but it's the only one I could find that was free and accepted donations.
