In FlowFast access is given to users to the Space. Several boards can be placed within a space.
If you have a need to restrict access to a particular board in a space, you should:
Create a new space ( button “+” when hovering over Spaces in the menu on the left);
Add a target board to this space (button ”Add” above -> Board from another space);
Select the target board;
Add users who should have access to the target board to this space .
You can either remove or leave the board on the initial space. Removing a board in the previous space will not cause it to be removed in the new space.
