I would like to change the email address that is shown when I go to the g-mail web-page. Right now I believe the email address that is there every time I go to sign into g-mail is considered the "default" and I cannot find the correct place to go to change this as we have multiple users of the computer. As the owner of the computer I would like my email account to be the default so that others have to delete my account name and re-enter theirs instead of the other way around.
