Tab: Marketing > Website. Two checklists (global only):

1. Fields to ask on Register – which fields appear on the sign-up form. Options: Name, LastName, Phone, Birthdate, Optin SMS, Optin EMAIL, Membership ID. Default: all except Membership ID.
2. Fields mandatory on Register – which of those fields must be filled. Default: Name only.

A field is only validated as required when it is ticked in both lists; a mandatory field that is not asked is ignored. Missing required fields return messages such as Name Required!, Last Name Required!, Birthdate Required!, Phone Required!. Birthdates are validated against your account's date-picker format.
