In Dryfta, you can control the number of seats within each session. People have to check-in to the session to occupy their seats on a first-come-first-served basis. A session can also be made accessible to selected user types only.
Once all the seats are filled, the check-in button is replaced with an add to waitlist button to let people add themselves to the waiting list. Those on the waiting list can be checked-in to the session only when someone checks out or when you add more number of seats.
