Hi David,
sorry for the late response - you posted in the wrong category (CComment instead of Matukio).
The bookingform is currently not that dynamic, you could just add another field Names of other people, but it can't react on the choosen number of bookingfields (not without changing the code).
Also, if the above is possible, on the back-end can you have each person listed separately so you can email each person individually even if only one person signed them up? For example, if the manager of a location registers himself and 3 people under him. I would like to later send an email from the back-end to all 4 people to remind them about the event.
I fear that's also not possible - in one of the next versions there will be an optional form for multiple bookings.
Best regards
Yves
