Save and continue later for previous users?

I already have name and email fields in my form, if I add the save and continue later feature, will those users be able to log in and update their info? Also, will we receive a notification when someone updates their submission? Finally, will updated entries be overwritten in the spreadsheet?

Hi,

I assume you are referring to this guide: http://www.jotform.com/help/97-How-to-Save-Forms-to-Continue-Later?

Using that guide, your users will have a session ID based from the email they entered, they can use a different computer or a browser and they will still be able to access the progress saved in their form. 

If what you meant by update their submission is using the edit link, then the answer is yes, as long as you have setup your email notifications properly.

If you have integrated the form in Google Spreadsheet, then the answer is yes, the submissions in your spreadsheet should be updated when the submission was edited and resubmitted.

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