[Vandivier]

user has three emails

1. primaryEmail (this is also your username and the main email for technical support communication)
2. backupEmail (for email lockout+pass reset)
3. stripeEmail

each of these three columns should be unique between users, but they don't need to be cartesian-unique (ie, the same email can be Jim's primary, Sarah's backup, and Ellie's stripe email)
