I apologize if I'm being really dumb about this, but I don't have a sidebar in the edit article form either:
Authors can't see their own awaiting-approval articles? That seems odd. What if they realize they left something out after hitting the publish button?
What is your screen resolution? 1024x768? Right now about 1 in 10 users have 1024x768 or lower as their resolution. GDNet requires at least 1088 pixels wide to get the full view.
Also my mistake when I wrote that response, authors can always see their own articles.
UPDATE: I addressed this problem with 1024x768.. you should be able to see the right column now.
