Answer 1

You may make your email unique in yii user model by the following rule as given in below.

public function rules() {
   return array(
     ...
     array('email', 'email'),
     array('email', 'unique', 'className' => 'User',
        'attributeName' => 'email',
        'message'=>'This Email is already in use'),
     ...
); }

Here className is the name of your user model class, attributeName is your db email field name.
