When you go to a concert, you share the overall experience with all the other attendees. That being said, every single person at the concert has their own personal experience too. Concert Archives embraces both of these different experiences!
The same "Facts" for everybody:
The "facts" of a concert (which bands played, the date, venue, location, setlists, etc) are the same for everybody. This is the information you enter when you create a New Concert or go to the Edit Concert page. The information that you add/edit here should be factually accurate and free of opinions because it affects all of the other attendees of the concert. When the facts of a concert change, each attendee is notified via email. Because the 'facts' are the same for everybody, anyone marked as an 'attendee' for the concert can edit the facts.
Your "Personal Experience":
Your "personal experience" of a concert could be totally different from other attendees! The Concert page is where you can share your experience and customize the concert. If you didn't see all of the bands that played, you can 'Select the bands you saw' to exclude the ones you missed. If you want to write down your memories or write a review of the concert, you can do that as a Comment (public or private). You can upload your photos and post your videos too. All on the Concert page.
