Can a respondent start a form, save their answers, and then come back and complete it later?

I'm going to be creating several fairly long forms (questionnaires) that may take someone several hours to complete. This is unrealistic in one sitting, so I want to see if their work can be saved and they can come back later and finish. Thank you...

There are 2 ways on saving the form and continuing it later. Please check these 2 guides:

How to Enable Auto Fill Feature - http://www.jotform.com/help/227-How-to-Enable-Auto-Fill-Feature

How to Save Forms to Continue Later - http://www.jotform.com/features/save-and-continue/

Please take note that the Auto-fill feature will save the data in the local browser, so it is only possible for the form to be continued on the same computer and same browser.

Let us know if you need any help. Thank you.
