Howdy Chip,
The tickets plugin is the easiest way to track registrants, because it allows them to RSVP or purchase a ticket and it allows you to export that data. You will note there are two tickets plugins: Event Tickets and Event Tickets Plus. You might only need the free Event Tickets for your needs, I’m not sure but you can try it out now and see if it works.
If you want to export the actual event itself, like the time, the venue, and the organizer’s contact info, then you can download it as an iCal file.
Does that answer your question?
Cheers!
