I am preparing to add an availability calendar for my group of professionals. Each member will have their own availability calendar. I would like to create a planner port where a planner could open a specific and consistent group of members calendars side by side. It would be great if the planner could then invite multiple members simultaneously to an event. A form email could be generated and sent. It would then be great for the members to select accept or decline and have their response update their calendar and send an email response back to the planner. One step further would allow the planner to indicate the request is "tentative" or "Confirmed" and then the calendars would be updated accordingly.
