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.
I think the root of their question is that they'd like to use JotForm as a service to create a form and then connect with another server. JotForm is a full service online form provider, in that you can both build your form, and also send your submissions to our server. From there they can receive notifications, view them online, etc.
We aren't a generic form builder that you can submit our forms to any server. There are other vendors who provide this functionality, and we recommend seeking them out.
So, in answer to your question. When users download the source code, they do 'own' it in that they're responsible for making sure it still works as expected, but it would require significant modifications to hook it up to another system.
Please let us know if you have further questions.
