I have a client that I am redesigning her website. It is a WordPress site. The business is a face-to-face national networking group. She does not want each area to get their own website. She wants the main site and wants to give them the ability to have where the "franchisee" can enter their own info for the calendar (would this be user roles?) and than have when some one clicks on the calendar, there would be a drop down box for them to choose the city and when they choose the city the calendar displays the events for that specific city only. How could I do this and what plugins would do this? It does not matter if they are free or premium plugins. Thanks.
