Enable this option to allow users to go back into their survey after completion to change their answers.
This can be useful if a respondent made a mistake or if information pertaining to the survey has changed and the author would like people to update their answers.
For email respondents, they can simply click the email link (or reminder link) to edit their answers.
If it is a web link survey, the respondent can use the web link again to edit their responses. Please note that if "Multiple Responses per Device" is enabled, web link respondents will not be able to edit their answers.
If Response Editing is turned off, email and web links, when accessed again by a user, will redirect to a page letting them know the survey has already been completed.
