This error message appears when you try to register yourself with an email address that's already in use. This error is displayed in order to make sure that no two members use the same email address. WizIQ doesn't allow any member to get himself/herself registered with an email address that is already in use. Also, you must make sure that you do not register yourself with an email address that you might have used to register yourself earlier on WizIQ or had entered it as the alternate email. If you try to do so, the same error message appears on your screen.
