What resources do you use, if any, to check out charities before giving money to them?
For example, I've used the following resources with varying success to find and rate a charity within the United States:
http://www.charitynavigator.org (I like this one)
http://www.guidestar.org/ (Requires free registration)
http://www.give.org (a Better Business Bureau site)
In the United States, charities that have over $25,000 of revenue are required to submit a Form 990 about how they have used money, etc. The GuideStar site seems to have these (and you can get the form without paying anything).
