Distinguish external user

Hi there,
I would like to share my sheet with other external users and set them as a ‘survey users’.
Is there any way that administrator can identify which external user add a certain information?

Thank you.

Hi,

Ragic will keep the history of a record for each time a user edit and save this particular record (including who do the action).
Clicking the i icon at the lower-right corner of the form page, then you may View the history of a record.
