            Send user email message (yes/no)
            Minimum period between popup dialogs (minutes)
            Minimum period between email messages (minutes)
            Add users to "To:" email list <email address list>
            Add users to "Cc:" email list <email address list>
            Add users to "Bcc:" email list <email address list>
