To start a quiz in a room, or to see the live results for a particular room, you'll need to switch over to that room. To switch rooms, click on the room name in the main header and select the room to switch to from the drop-down list.
Want to change the rooms available in this list? Click on the Rooms section, then check/uncheck the box next to the room name on the left, to add/remove it from your room name menu.
You can also switch rooms by clicking the room name from the list in the Rooms section. The room you are currently in will appear bolded in black.
If you have an activity running in any of the rooms, the status icon will appear animated. If you need to end an activity, you can finish the quiz from the results page.
