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.
You can share your JotForms with any one of the other users as a sub-user. You can invite them by using their email ID so that they'll be gaining access to your JotForms as per the rights provided by you for each/all JotForms. You can create the sub-user account from Users tab (http://www.jotform.com/myaccount/users) in your account section.
Please refer to the following guide that can help you in this regard.
Please let us know if you need any further help. Thanks!
