Hey there, and great questions!
You can indeed set a cut-off so that tickets and RSVPs start and end on specific dates and times. You can also set a maximum number of stock for each ticket to limit sales.
Events Calendar PRO does offer recurring events. However, I do want to note that recurring events do not current support ticket sales at the moment, though we are working on it.
Why Your Form to Post Event shows other organizers?
It provides a way for people to submit an event with an existing organizer to prevent duplicate organizers from being added to the calendar. You could hide that portion of the form altogether with some custom styling in the CSS.
Does this help answer your questions? Please let me know.
Cheers!
Geoff
