User Data add-on boosts your PrivateContent plugin allowing you to create and use unlimited fields to record more informations from your users. A powerful but yet simple wizard will guide you creating them. Then, will be automatically integrated in the PrivateContent engine and ready to be used in registration or custom forms. Each field is dynamically validated and is also really flexible, letting you target what will be required. String length, numeric ranges, multi-option checks, preset texts (integer and floating mubers, e-mail address, dates, url, etc) and also room to use advanced regex. Say goodbye fake data stored!
