Public survey but with contributor's information (public account)

Question asked by n.ueberschaeresri-rw-esridist Employee on Oct 24, 2017

I would like to publish a survey for crowd sourcing data. Still, I would like to somehow know at least the name or an email address of the contributors to see if they added data before or how reliable the information might be. For this, limiting the survey to people with a public account (besides named users) seems to me the best solution but how could I achieve this limitation?


Thanks in advance!
