Simple Event Plugin with Themify
The event post plugin that comes with the Pro version of Themify is great for posting and managing events that don’t require a calendar view or other sophisticated features. It does allow for recurring events, which is super! And using the Post Type Builder the page view of the Events can be modified to your liking. (Nope. This is not true. I need to ask for more details about this, but the default Events page does not appear to be accessible. It would have to be built using the PTB. But the event taxonomies are also not available. Better to build your own event type modeled after theirs and have all that.) But the real key missing element is there is no attendees list created.
I think EventPrime will give more bang for zero bucks.
Take a look here.
