Hi Homer,
Well, if you’re looking to do that with Eventbrite, you’ll have no luck. Eventbrite keeps all the information about attendees in their system and not in WordPress. However, one of our other plugins, such as Woo Commerce Tickets, may be able to do what you’re asking. Woo Commerce Tickets stores attendees (and their information) in WordPress. The query on attendees across events is not something that is included and would require customization, which we don’t provide.
As far as the cost goes, yes, each plugin would be a separate purchase. But to be clear, you do not need PRO to use a ticketing plugin. You would only need it if you want the functionality that PRO provides.
Does that make sense? Will this work?
