Not to hijack the thread, but i think it will add a different approach to the original question.
I would like to use Jotform inside a users account, so the following steps
1. Register on my site using my sites account creation.
2. User fills in a Jotform with their details and more.
3. Update the form when inside their account at a later stage.
Is Jotform able to identify the user and present their information?
