Hey Dan,
Thanks for reaching out to us!
We do have an attendee list that can be managed from the backend. The only thing to note here though is that as users are added or deleted manually there, you may need to update the available stock within the associated product (via WooCommerce or your other selected cart available) so you aren’t able to oversell the event via the website.
Also, we are still currently in development for Tickets Meta. We don’t have a set timeline just yet for it though.
Let me know if this helps.
Thanks!
