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.
If you submit the actual form multiple times every time you press submit button new submission will be sent. So if same user submits your form few times submissions will not be overwritten.
Submissions can be edited only from your account or from edit link inside of notification.
Hope this will help. Let us know if you need further assistance.
