Can a form be partilly filled out and saved and returned to later

Hi,

Yes, that is possible, there's two methods that you can use:

Method 1: Use the Auto Fill feature.

Method 2: Using the email as a session ID, here's a guide: http://www.jotform.com/help/97-How-to-Save-Forms-to-Continue-Later? 

I prefer using method 2, it gives your users the option to continue filling out the form on any computer, as long as they have the session URL with their email address as mentioned in the guide above. Method 1 only stores the progress on the actual browser and it may load previous sessions of other users if they are using the same computer and browser.

Do let us know if you need more information on this.
