That label is too visible. Some users misunderstood what it is for, and post messages on board description instead of creating a topic. Or it is just vandalism.

I suggest to have that link moved to the bottom of the description.
It may partially solve the unscheduled T113902: Add option to semi/fully-protect Flow board descriptions.
