EDF is one of the "5 Environmental Charities to Support." When I clicked on EDF on that page, I was sent to a page collecting money. How do I contribute points? And how much is, say, 100 points worth in cash? Shouldn't the "exchange rate" be on the "5 charities" page?

I've always donated my points to Habitat for Humanity - now I can't find it on the site to do that - ???
