Your primary address is the email address you use to log in to FOM PortfolioBuilder and is the one we use for any correspondence. It is also the email address we would use if you wish to reset your password.
We have made it so that you can add as many email addresses to your FOM PortfolioBuilder account as you wish. We included this feature because sometimes trainees nominate users for an assessment using a different email address to their primary one. With this feature in place, it doesn't matter which of the linked email addresses an assessor is nominated with, the nomination will still appear on the assessor's dashboard.
