During a Zoom tournament, your staffers will typically each be in a different breakout room. You cannot be part of multiple breakout rooms at once. This makes it difficult to have a “control room” in Zoom. While you can create a dedicated breakout room for this, we suggest that you instead use a separate communication method for tournament staff.
For instance, you could create a Discord server just for the staffers, or you can use any existing group messaging app. This will allow your staffers to switch between games (in Zoom) and staff communication (elsewhere, in a different window or tab).
