In Agenda, open Rooms and click Add Room. Rooms are the physical (or virtual) spaces where your sessions take place, and they become the columns in your Schedule Builder. Start with:
- Room Name — e.g. "Main Hall," "Room A," "Virtual Stage"
- Capacity — how many people the space holds (leave empty for unlimited)
- Description — floor, building, or any notes worth showing attendees
You can reorder rooms with the up/down arrows. Deleting a room leaves its sessions in place but unassigned, so you can re-home them.
