Translations:View saved but not submitted responses/23/en
From LimeSurvey Manual
The following fields are displayed: name, password, repeat password, and email address. Out of the four fields, only the "email address" does not have to be filled out (it is useful to ensure the anonymity of your respondents). But, if it is not filled out, the respondent will not receive any email with the data he filled out on this page (the user name and the password he used to save his response to be accessed later). Therefore, he has to either remember the name and the password he put in the boxes or to save the data locally on his machine before clicking the "save" button.
