Hey Wendy and thanks for reaching out!
Good questions:
Is it possible to create a map that shows ALL locations from all events on a particular day?
Yes. PRO does include a Map View and you would be willing to drill that view down to a specific day. You can make that even easier to do on the front end using our Filter Bar add-on, which allows users to display events on particular days and times, among other variables.
Is it possible to list multiple organizers for an event?
Absolutely. You can add multiple organizer to any single event.
Is it possible to change the name of “organizers” to something else?
Is it possible to change the name “venue” to something else?
Yes on both counts. In fact, we have a nice article on how to do just that.
Does this help answer your questions? Please let me know. 🙂
Cheers!
Geoff
