Example director link:
Corresponding room link:
There will be a new button added to the director's view, which when pressed, loads a guest into the director's room. The guest will be able to see the director and only the director then. The director can add more guests this way, kicking out those they don't want, and continue to cycle thru the queue of guests as they join the room. The director can then Transfer the guest(s) to another room, and when transferred, the guests are no longer considered in 'a queue' and will be able to see everyone in that new room, and vice versa.
