Does anyone have a solution that would prevent the duplication of Users in the Users object? There is no option to make the username or e-mail address unique. ---

You’re right Brad. Just tried to duplicate and it would not allow me to add another user with the same e-mail address. I believe that the duplication that I came across was on an import of users into the object. ---

It's built in already I thought - if a user tries to add a new account to your app using an email address already in use a validation error stating 'Email must be unique' appears. This isn't happening for you?
