See
https://www.jevents.net/docs and the FAQs menu item above.
We don't provide documentation for club addons to non-members but you can see some of the features via the products menu item above.

You can use JEvents for free and if the club addons do not do what you need you can request a refund up to 30 days after joining the club,
