Sunset (or disable) a board
First you need to vacate each seat, then you can disable the board. This will move the board to the bottom of your Admin list page, while keeping all the information intact.
To do this, go to the board an click Manage.
Use the action menu for the first seat and use Vacate Seat. Enter the End date (required) and the Reason (optional) the seat is being vacated and hit Submit. Now repeat this for each seat on the board. Once all seats are vacant, you can sunset (or disable) the board.
Now at the top of the board page use the Action button (next to Edit Board) and select Disable Board. The board will show in yellow in the Admin Portal and be hidden in the Public Portal.
Municipal Admins will still be able to access this board and view all information about the board and members. Reports will also include disabled boards - unless the disabled board has been intentionally deselected in the report.
