I created an Extra Widget Area (called "Category:News left") to be exclusively used by our blog page. The blog page has a category = NEWS.
I added the Tag Cloud and Newscast Advertising widgets to this Extra Widget Area.
Category "News" is excluded from the home page, as are all other categories except one called FEATURED.
Both the Tag Cloud and Advertising widgets are displaying on the Home Page here: at http://22.214.171.124/~integry3/
Am I missing a set up step?
