What Pro adds

• Registration forms (Members Area > Registration forms): several forms, each with its name, the Role given to new members, the Extra fields to ask and a Page after registering. Use [nopdma_register form="slug"] or the option of the Register block. The roles on offer never include administrators or roles that can manage the site, and the choice is checked on the server.
• Manual approval, groups and extra fields (Members and groups, Registration fields). Each field can be made public or private.
• Restrictions (Settings > Registration): Allowed email domains, Blocked email domains and Forbidden names, also on email changes.
• Roles (Members Area > Roles): page after login and after logout, admin bar (Default, Show, Hide) and wp-admin (Default, Allow, Close) for each role. Roles that can manage the site are never locked out.
• Advanced members list: group, filters="role,group" for a menu visitors can use, orderby="random" and search in the public fields.
• Import and export: Import members from a CSV with preview, rejected rows with the reason and random passwords (email, role, group and a column per extra field); CSV export of the members.
• Editable emails and unlimited access rules.

Without a licence the Pro data stays saved and simply stops applying: Pro forms behave as the normal form with the default role.
