Hi Martin,
Community Tickets currently requires Event Tickets, Event Tickets Plus, and WooCommerce to be installed and activated, but you can disable the ticket sales with a customization. We are a bit limited in the amount of support that we can provide for customizations, but this post has an example that should help get you started.
Users can indeed login and see and export a list of attendees for their events. This article has some more details on how this works.
We do offer full refunds within 30 days of purchase, so if you’d like to take Community Tickets for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
