I am not sure on how to remove an email address however with being in the uk I spoke to
a person from the wow met office and they removed it for me, but It still caused a few issues
so I just re-registered on another email address as they are easy enough to do.
then if you are sending emails out on your old email address just include the new
email in the signature below.
