I'm sure you've seen the horrifying images on TV of destruction left by Hurricane Katrina, and the many, many people left with nowhere to go.
You can help. MoveOn.org just launched a website, www.hurricanehousing.org, to connect your empty beds with hurricane victims who desperately need a place to wait out the storm.
You can post your offer of housing (a spare room, extra bed, even a decent couch) on http://www.hurricanehousing.org or search there for housing if you need it.
MoveOn will pass requests from hurricane victims or relief agencies on to volunteer hosts, who can decide whether or not to respond to a particular request. The host remains anonymous until they reply to someone looking for housing.
I just posted my own offer. I hope you will too, or pass this on to people you know in the Southeast:
