My friend cleolinda, who fortunately was not hit by the storms directly, but lives really close to areas that were, has done an excellent job of providing news, links, photos, videos, and most importantly, ways to help on her journal. So I am going to direct people over there for more information on all of those things. There are ways to donate money to the Red Cross, ways to buy or donate auction items for fandom and literary fundraisers, and more.
Please go and read these entries, and then if you can manage to help in some manner, please do. Our friends in the South need us.
