How to have form emailed to person completing it?

Where is the setting/option to have every form sent to the person filling it in as well as to me?

You can find the Email Notification and Autoresponder Email in the "Settings" under "Emails". The Email Notification is the email that you will receive when someone completed your form.

The Autoresponder Email is the confirmation email that the submitter will receive after submitting the form.
