I want to activate the automatic subscription to 10. Give a name to the data but after what I go step basis, which is the automatic registration

I read here:  If you intend to enable automatic user registration, so that visitors can register themselves and obtain a login and password for accessing locked pages, you first need to set up a database in which the registration data will be saved:

§In Step 4 - Advanced Settings, click on Data Management.

§Click on the Add... button to open the Database Settings window and enter the necessary information for setting up the database you intend using for access management.

When the database is set up, you can enable automatic user registration:

§In the Access Management window, go to the Settings section.

§Select Automatic Registration as the Registration Mode.

§ In the Settings section, select the Database to be used and enter the name of the Table Name where the data will be saved. You also have to specify an active e-mail address in the Admin e-mail address option: requests from users who have forgotten their password and/or new registration alerts will be sent to this address.

§If you want, you can also enable the appropriate options so that the administrator receives a message each time a new user registers (Send an e-mail to notify new users subscription), the "Captcha" anti-spam filter is added to the bottom of the registration form (Enable 'Captcha' anti-spam filter) and an e-mail address validation request is generated (Enable E-mail Address Validation)

Where is 

§In the Access Management window, go to the Settings section.

§Select Automatic Registration as the Registration Mode. ???
