Forum Suggestion: Allow Users to Block Topic Areas

After learning of what is involved with phase 2 of SoD, I’m not liking it. So I no long want to see that particular area of the forum. Is there or there should be a way to block or hide that category? Most forums have a small up down arrow at the top right of each topic/category area, clicking this arrow would open or close that area, then it could be saved afterward.
