Is there a way to delete the "create your own jot form" from the thank you section?

If you are in a Free Plan, unfortunately, you can't remove the JotForm footer. You need to be in a Paid Plans in order to remove the JotForm branding on the Thank You Page. 

To remove it, please go to your My Account Settings: https://www.jotform.com/myaccount/settings. Then, scroll down to see the JotForm Footer and uncheck it.

Let us know if you need further assistance.
Regards.
