How do I enable multiple submissions for a form?

This form will be going out to a small hand full of people to re-submit over and over. Therefore, I need to enable multiple submissions for this form but I am not sure how. 

To enable form element you need to select the option "No Check" in Unique Submissions settings.

1. Log in to your account and open the form.
2. Go to the Settings section page and select the Form Settings tab.
3. Click the Show More button.
4. Under the Unique Submissions drop-down menu, choose the "No Check" option.
