Paneling/Rooms
Mass Assign
If you didn't auto-assign rooms during the paneling step, you can assign rooms to a speech event using the "Rooms" menu option, and then choosing a timeslot on the sidebar. The "Mass Assign" tab will show you a listing of current assignments, and the option to auto-assign the rooms in that timeslot
Pools
To create a room pool, click the "Create New Room Pool" link on the sidebar and then give it a name.
