Can I configure forms so that users can save intermediate versions of filled forms and go back to work on them later?

Can I configure forms so that users can save intermediate versions of filled forms and go back to work on them later, or share a link so that others can complete the form?

This would seem like an extremely useful feature, but our local Emory users of jotform have not found it possible to date.  

Yes, this is possible. You may consider the following options available in JotForm:

1) Enable an Autofill Continue Forms Later option.

- How to Enable Auto Fill on Forms

* This option saves answers only for up to 24 hours in the user's browser.

2) We offer web forms in classic and card layouts. If you select a card layout form, you will be able to easily enable a session-based 'save and continue later' feature:

- Setting up the Continue Forms Later Feature in Card Forms

With this method, the data is saved for up to 90 days on our servers. It can be accessed from any device using an emailed session link.

3) If you select a classic layout form, the session-based continue later implementation will be a bit more complex, but still possible:

Additionally, the submitted form entry can be updated if you share the 'submission edit' links:
