Hi Frank,
Thanks so much for your interest in our plugins! 🙂 We absolutely can (and do!) support online-only events with The Events Calendar and Events Calendar PRO–though venue options and Google Maps integration are provided for users who wish to utilize these features, they’re not required fields, and you can easily sidestep them when creating your own events. Instead, you might simply provide a link to a relevant site in the Event Website field, or, if you’re using Events Calendar PRO, you can use the Additional Fields feature to add unique fields for your events. I’d be glad to answer any questions you might have about these or any of our other product features!
I hope that helps! Thanks again for stopping by, and let me know if there’s anything else that I can do to assist!
