I see that you have just created an account with JotForm and it is on a free subscription. However, if I'm understanding your concern correctly, you have submitted a form that is created by one of our users in JotForm. If you wish to contact the owner of the form that you submitted, I suggest that you check the email you received and look for the "Reply-to" email address. You can use that information to contact the owner of the form.
