Uni 101 site wanted no left column. I used the administration/site configuration and tried to set the block for 07-secondary-navigation to "no block", but when I submitted that change, the configuration appeared not to be updated (i.e. the path to the block still appeared there) and the page itself still allocated space on the left side.

Wrote to JS, and she said she set 07-secondary-navigation and 08-quicklinks to "no block" and that generated the desired effect. (The site configuration now shows empty for those two content areas, and the actual page shows the main content area extending to the left edge.) I still don't understand what caused the behaviour I got. I did not set 08-quicklinks to "no block", so maybe failing to do that causes Cascade to ignore the fact that I did set 07-secondary-nav to "no block". I haven't tested that.
