JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
What you are looking for Corey is the edit link. You can give this link to your users on your thank you page, in the email autoresponder, or you can have the link be sent to you so that you can send it to them manually if so needed.

Of course, if you happen to have any questions, we are here, so do let us know :)
