In reading back through the link, it never says whether they mean ICRC or ARC. I'm going to assume that they are talking about the ARC as it's for the Super Storm Sandy disaster but I don't want to put words in their mouths.

At fandomaid, they make a great list of charities (both local and more widespread) for each disaster that they set up an auction for. I'm always highly impressed with the varied types of charities that it is possible to donate to. I would never tell anyone NOT to donate to the American Red Cross (as a donation is a donation is a donation) but there are so many other places that don't get the sort of press that the ARC does that are, perhaps, a better option.
