Collect additional information

If you'd like to collect additional information, you could use our Redirect URL to send the new member directly to a more complex form (using a WordPress form plugin) after they sign up. This form can be submitted and tied to the WordPress user.

From your Memberful dashboard, navigate to the Plans tab, select a Plan, and click Plan Settings. Then specify the Redirect URL.
