Hi Ives
I found one "bug" (or may be just wrond configuration)
after all available places are booked, new reservations goes to waiting list as expected.
But if someone cancel his /her booking, reservations from waiting list are not going to be booked.
There is free place and new student can book event.
It is as designed, or I have some misconfiguration here?
Thank you for answer.

Michal
