Moveon.org has a website called
Hurricane Housing which lists shelters, organizations and families that are offering short and long term shelter. Even tho we are in vegas we added ours as we have a spare room and who knows.. at least vegas has jobs.
Also Craigslist.org is posting information for NOLA and surrounding areas about housing, food, jobs etc and i think they were starting a "here is where I am" list.. for those who are looking kind of like what they did after 9-11.
