I.E. to not include information about who it was that filled out the form.
If you wish to make a form anonymous you can do the following steps:
Create a new form or open an existing form that is in 'Draft' mode (not published).
Inside the form you have the preview section on the right-hand side, now select the tab 'Template Options'.
Under 'Template Options', check off the alternative 'Enable anonymous reports'.
Remember to save the template when you are finished.
