Does anyone know of an easy to use site that evaluates charities on the best/biggest impact? A while back (possibly a few years ago...) I saw a (some?) threads that discussed this. I seem to remember the charity rating website suggested some specific charities that gave mosquito netting or provided clean water. I can go search for those types of charities, but I'm wondering if there's some independent evaluator out there that is solid and easy to use.
