Our laptop is used by the family, so there are a number of user id's (email addresses) that come up when one of us clicks on the box to enter

our individual address. Unfortunately, when some of the email addresses were originally entered in the set-up process, mistakes were made in

the spelling or construction. These were corrected and re-entered, but the incorrect entries remained. Subsequently, when one of us clicks on

the address box to bring up the list of our email addresses, all the incorrect ones are there as well. How can I remove them?
