Releasing my superstition that ''Worry'' equals an invitation
  for something to happen, I registered with the Red Cross' ''Safe
  and Well'' site. Although I have not suffered a disaster, and
  hope I never do, I think it is a good idea that the organization
  that would probably try to find you, should have at least SOME
  clue where you last were. And, if there is some sort of disaster
  that displaces you from your home, you can then update your
  entry when you are safe. While they record your
  name/address/phone number for themselves, they do NOT display
  them on the site. Just how safe you are and a custom message you
  can put on.
