Hi Frank and thanks for getting in touch!
Good question. I’m afraid the additional fields do not add the functionality you are looking for. They will additional additional fields on the back end when publishing new events, but they do not collect additional information from anyone who purchases tickets through the site.
We are working on a feature to collect attendee information but it will be a little ways out before that gets released.
Sorry about that, but does this help answer your question? Please let me know.
Cheers!
Geoff
