I'm OK

A website called I'm OK has been set up for people in the Katrina affected areas of the US to register that they are OK, and where friends and loved ones can log in and see who is registered in the database. Other sites such as the Red Cross are doing the same sort of thing, but it is supposedly quicker and more accurate because it uses the person's telephone number as the main search criteria, speeding up the searches. If you know someone in the region, it might be worth checking this out in addition to the Red Cross's Hurricane Katrina register.
