How can I see who submitted their testimonial?

You can check this following this guide: https://www.jotform.com/help/269-How-to-View-Form-Submissions

I hope this helps. 

This does not help. It doesn't give an email address or name. That is what I'm wanting to show. 

Hi,

Are you referring to this form, 200336111942039? The only way to know the form respondent's information is to add an email address field or name field on your form. Then all of the data submitted by the responder will be shown on the submission's page, as advised by my colleague. 

I hope this helps. Let us know if you are referring to a different query.
