How can I show the name or email address for responses to form survey in the results spreadsheet? We want to see each other's responses but results sheets seem to be anonymous and only show time stamps of responses, but no identifier.
One way is to add a name/email-id field at the start of your survey. This helps identifying the responses.
Only Forms for Google Apps for Work or Education have an option to automatically record the username of the respondent but it's is limited to users of the same domain as the form creator 1.
One alternative is to add a question asking for the name of the respondent or any other information to identify them properly.
