It's an excellent solution (Again). Sadly, it's not applicable here. I
*do* need a unique validation for the update form, to prevent user a to
be using user b's email. One solution is to not pre-populate the form
with values from the DB, or place them in labels. But before we try
those changes, I want to make sure there's not a way to use the current
configuration.
