Aren all the contact information entries for events, venues & people redundant?
No. The contact information fields are meant to be tied to the specific event, venue or person and in general should be different from each other: Event: the person(s) running or organizing the event Venue: the person(s) in charge of booking for that venue Bands/DJs/Instructors/Performers: the person(s) in charge of hiring these performers The idea is that other event organizers can have info for booking venues and performer at their disposal.
