Hey @ProfRoger ,

You can ask for Names and Emails of those joining your event, or if you are on a paid Professional plan you can set up SSO for your participants.

Once your participants join the slido, when you activate the Quiz, it will prompt your participants to “Join the Quiz” in which they will enter their name, or it will automatically have their name from what they joined the slido using). Once all your participants join the quiz, it will display their names on the screen to see who has joined already. From there, you can begin running your quiz.

Let us know if this helps or if you have any other questions.

Best,
