Hi Alan,
Just to clarify: you want to list all attendees on the single event page?
One thing I’d point out is that this would really boil down to a list of names of those people who purchased tickets – so, A) the purchaser in each case might not be the same person as the attendee and B) if someone buys 5 tickets on behalf of a group we’ll still only have the name of the person who made the purchase.
So, while it’s definitely something that would be possible to do (and sounds like a great idea) I just wanted to appraise you that there are some possible downsides, too.
