I’ve looked at the plugin page and when used with the Pro version the following is not clear…
1. Is a dropdown presented for selecting the Venue and Organizer?
1a. If yes and the venue and/or organizer does not already exist can you use a ‘new one’?
1b. If yes is the new venue and/or organizer saved for future use?
I’m sorry you’re having trouble finding the information you are looking for. To answer your questions – YES, to all of them. There is a dropdown for both the Venue and the Organizer. When you enter information, it is saved and added to the list, and you can add a new one anytime. Plus you can set a default value for both of those as well.
