Hi Jay,
Thanks for your interest 🙂
Does the premium version offer the ability to schedule events without specifying an end time?
This is actually possible with our free, core plugin – and yes, Events Calendar PRO follows suit.
Also, some events do not have a listed organizer. Does the premium product offer the ability to disable the organizer info?
Again, there’s no particular difference between the core and pro releases in this regard: if no organizer is specified, neither try to display organizer details.
I hope that answers your questions 🙂
