Great! Thank you for the quick reply! I think this is clear to me now. It´s not even possible to conduct a closed survey without using a unique token. To summarize this:
In a closed survey, I´m able to manage the participant table, send targeted reminders and a unique invitation (Dear....), the only difference is that the name and answers are not merged in the answer table, which is the case with a "normal" token. Am I correct?
