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.
I went through the answers of your original thread. Do you want second person to also sign in your form? Please be noted that to be able to capture the user's signature, form needs to be submitted and it won't be possible to make the form's editable for just one user. I will still go ahead and make few test and get back to you if I am able to find any solution for your requirement.
Thanks Ashwin and Jotform team you have been very helpful!
