Once, the page is created, you can drag the Portal User Creator widget from the Portal Connector widget list located on the right-hand side of the page. 

You can press the "Edit" link on widget to enable/disable Captcha or to set an initial portal role that will get assign to user on Registration. 

Note: When a user submits the registration, the portal creates a contact record, portal user & portal user role record in CRM for him. If the contact record already exists in CRM for user (based on email address matches) then portal will link his registration to existing matching contact record, and will create portal user & portal user role records only. Although, in the case where the contact record already exists in CRM, after the user record has been created, for the security reasons, the user will have to use "Forgot Password" option to receive credentials on his/her email address to validate his registration against an existing contact record.
