Hi, Greg. Thanks for asking about our Facebook Events add-on.
Facebook Events is a fully-featured event importing plugin that extends the capabilities of The Events Calendar. For a complete overview of its capabilities, please check out our product page for it: https://tri.be/shop/facebook-events/
That said, the functionality you’re looking for seems to be aimed at two-way communication with Facebook, which our add-on cannot provide. Unfortunately, for event management beyond importing events created in Facebook, you would need to be on Facebook’s site. I believe this is because of restrictions in Facebook’s API, but I’m not certain about that.
I’m sorry that our product doesn’t seem to be what you’re looking for. Please let me know if you have any further questions about it.
