Allow multiple e-mail addresses within a single user profile
Many of our registered users have multiple accounts because they want to receive e-mail notifications at more than one e-mail address. Most have a home and a business e-mail address. Some have more than 2. It would be useful to allow users to enter a primary and at least one alternate e-mail address. You could allow them to specify if they want e-Alerts sent to all addresses or just the primary address.
