The Patron Event System will allow sites that have events that require tickets sales by the host membership to track all patron purchases and provide the ability to produce advanced tickets sales flyers and on-line ticket purchase forms.
When membership is responsible to sell tickets, they end up maintaining their own marketing list and don't provide it to the organization. If the member moves away, the patron list he/she sold tickets to is lost forever.
