Who ISN'T wishing there was something they could do to help the folks in New Orleans and MS? (Okay probably somebody, but I don't want to hear from you, because you suck)
Larry Dixon, the husband of my all-time fav fantasy author, Mercedes Lackey, has a website about Katrina. He was all set to go down and help (qualified as EMT, etc) but they don't want people coming down! So he's shifted gears and is trying to help re-locate people who have gotten out and have no place to go.
