A real and entirely non-comforting email I received this evening:

Dear CLEAR customer,
We may have sent you an email notification on 7/21/2010 or 7/22/2010 indicating that your account information had been updated. If you did not make any changes to your account, please disregard this notice. It was an error on our part, and we have since corrected the issue.
We have verified that the information on your account is correct. No action is required on your part.
We value you as a CLEAR customer and apologize for the error.
Sorry for the inconvenience.


On a brighter note, since we moved across town, our connection is working better than ever. 5×5 with no leaning out the window!
