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.
Please noted that when you enable encryption of form, auto-responser email alert will no longer work. That means the user will not receive any email from form and no submission PDF will be sent.
