What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
Sub user account or sub account user is an account that has access to another (main) account that holds the forms.
This is a great way to have someone come in and help you with the design of the form (such as form designer, or web designer) and in the same time to not allow them to see the submissions made on the form.
This means that the data you get is your alone, while in the same time you do not need to worry about styling of your forms.
The same applies to people working for you that might need to access form submissions to do their work, but you do not want them touching and changing your forms, you simply allow them to touch the submissions only.
Now you can also allow access to both or fine tune the access to some folders, forms, etc, but overall it is an option that is there to allow you to give more access to others, without giving access to your account, your billing part of your account and to anything that you do not want to share.
