/**
 * TEC + CE + CE Tickets: If Split Payments is enabled and user does not have their payment email address filled out, show notice at top of Community Events form to alert them to complete their split payments profile before creating an event... because they cannot create a ticket for their event until they do so.
 *
 * Note that this may not be what you want if not all of your event creators create tickets for their events.
