Can this be used for class registrations?

you can see the demo page at https://demo.wp-events-plugin.com/events/josh-groban-2017-10-31/

also, incase of some issue EM developers are willing to look in your site to debug and fixed the issue; however, we are quite limited with regards to custom coding and troubleshooting other plugin or themes.

So what you’re saying is ‘we don’t have a demo showing EM being used for class registration.’

EMPro supports multiple bookings mode however booking the entire class or recurring events at once is not available at the moment.

Thanks for clarifying.
