Hello! I thought I'd post the websites I'd located thus far that are set up to help match up families and survivors with those who want to take people in.
MoveOn's www.hurricanehousing.org
there is also www.craigslist.org
operation share your home: www.shareyourhome.org
and www.katrinahousing.org
This last one also has a couple message boards that allow people to post their info again, and alot of people agreeing to drive survivors to where you are, or help pay for gas etc.
Another idea: for those who live very far away from LA, some people are usng their miles to fly survivors out to live with them, like one family in No. CA.
