Only the GVO Manager can delete a board. This is an irreversible feature - once deleted it cannot be recovered.
To delete a board...
1. Go to the Board list
2. Select the board you wish to delete and click on it...
3. Press 'Edit Board' (top right) - this will open up the list of users to add/remove from the board.
4. Make sure all the names are unticked
5. Scroll to the bottom of the list where the 'delete' option is located.
6. Enter 'yes' (lowercase yes ... without quote marks...just the word yes) in the box and press 'Delete this board'
The board will now be deleted and will not appear in the board list.
Note: You cannot delete the board in a single school GVO and you cannot delete the Trust Board in a MAT GVO.
