Add a notice
Go to Notices and press Add notice. A notice has a Title, a Message, an optional Photo, and the dates it runs: Starts and Ends. It shows from the first day until the end of the last. Leave Ends empty to keep it up until you remove it.
The list shows when each one Runs ("Oct 2 to Oct 5") and whether it's On the TV: "Running now", "Starts Oct 6" or "Ended Sep 28".
On a board
The Notices item shows the notices that are running, one large and the next two smaller ("Next", "Then"), taking turns. Choose its Layout (Big one on top, Big one on the left or Big one beside its photo) and how many seconds each leads. Under More options, When a message doesn't fit: Scroll through it or Page through it.
Notices are shared: every board with the item shows the same ones. You can edit them from the item's panel, under The shul's notices, or click a notice on the board to open it there. Changes save as you type and reach the screens on their own.
Delete
A deleted notice goes to Recently deleted for 30 days, with Undo straight away.
