BFP and Sylvia have done a wonderful job of linking to ways to help/who can use your help urgently. Kevin has them, and more, rounded up here.
Also, I've had an e-mail and a comment asking about my family. My immediate family lives a few miles south of Arkansas, so should be physically safe. I do have an aunt in Iota whose daughter lives in New Orleans and whose son attends UL-Lafayette, and two other cousins, one an undergrad, one a law student, at Southern in Baton Rouge. I'll be calling shortly, but as far as I know, we're all safe and sound. Thank you so much for asking.
