GulfCoast News has a Katrina Survivor-Connector List where you can post news and get news for loved ones in the area. This is where I was able to get a hold of Boomr's cousin. If you have any news about someone that someone else might be looking for, please leave a note.
Also, Carson is helping to find refugees places to stay in the Atlanta area. If you know of anyone who is looking for shelter, go over to Carson's and e-mail her.
