Hi @DeniseG ,

if you want to collect email addresses, you can turn on “Require email” in your privacy setting. Check this article on how to get participants’ names  and emails for a step-by-step guide. :)

With the “require email” on, your participants will be asked to submit their email address when joining an event. Their email address will not be displayed publicly, but you, as the organiser, will get the list of email addresses in an export.

I hope this helps. :)
