Julio, there is a menu bar near the bottom of the page that contains a drop down menu window that displays 'Discuss Cooking v2.0.
Open that window and switch to the other option - v1.0. Then the 'turn off right column' option will show up as the last item on the edit options page. Change that as you like then you can switch back to Discuss Cooking v2.0
