Hi Kieran,
Thanks for reaching out to us!
Those are great questions. I’m happy to answer them for you.
Can you have two types of events: open & closed
This isn’t possible out of the box, but it is probably doable with either customization or a third party plugin, which allows you to determine whether an event (which is a custom post type) can be viewed by anyone or only members. We have a number of users who are using WooCommerce Memberships successfully.
Who has the ability to add events?
It works like posts, so if a user has the ability to add a post, they also have the ability to add an event.
can an invite be sent to the members who can attend?
No, this is not a functionality of our plugin.
on the demo is shows tickets, could it be customised to show book now as well as on the confirmation emails that get sent?
Yes, it is possible to customize the texts on the site as well as the text of the confirmation emails, though that requires a bit of coding, as there is no user interface for that.
I hope this answers your questions. Let me know if you would like to know more.
Cheers,
Andras
