When you join an incident, you will see the Whiteboard or Public chat at the bottom of each room.
If you can't see this, then see Why can't I see Whiteboard or Public chat?
The Whiteboard is made up of three sections.
1. The comments history - you can scroll through to see the previous comments. The lastest comment is at the bottom of the list.
2. Users who have opened the Room
Users with a Green Dot shows they are currently in the Room.
Users with a Yellow Dot have the Room open but are currently in another Room. They will only see your comments when they come back into the Room.
3. Text Field to enter your comments
Remember, this text is visible to anyone who joins the Incident and opens this Room.
