Any other director using the same room name and matching co-director password can join as a co-director.
The first valid director in the room remains the main director. Co-directors inherit most director tools, but the main director remains authoritative and cannot be removed or controlled in the same way as other guests.
Current behavior
Co-directors can share most director controls
The main director remains the authority
Some controls remain restricted to avoid conflicts with the main director
Queue and held-guest state is synced from the main director over the normal shared-state path
That last point matters for &queue: late-joining co-directors should still see the current "Activate Guest" controls for held guests, and activating a guest from a co-director routes through the normal director activation flow.
Optional room-settings workflow
You can also enable co-directors from the room settings panel, which generates a co-director invite link for you.
Warnings
Do not reuse the room password as the co-director password.
Co-directors can only join if the main director has enabled co-director mode with a matching password or room setting.
If the main director leaves and rejoins, co-directors may need to reconnect and revalidate.
If duplicating a director URL into another tab, remove any existing &push=STREAMID value first, since each participant needs a unique stream ID.
&view can still be used to intentionally exempt specific stream IDs from queue behavior, but it is no longer the recommended workaround just to let co-directors see queued guests.
