A board is yours until you share it, and then it is open to exactly the people you named.
Every new board is yours alone. To share one, put it on a team and name who on that team can open it.
An Editor can change everything except deleting and sharing. A Viewer reads everything and changes nothing.
The Owner alone deletes a board, shares it and hands it over to someone else.
Add people, build teams and set roles in Settings. One person can be on several teams.
See every board you can open and who else can open it, in one place.
A green dot beside everyone who has signed in, a red one beside anyone you invited who hasn’t yet — and when each person was last seen.
Each organization’s data is kept apart from every other organization’s.
