The WP Voting Contest creates it's own sidebar in WordPress > Appearance > Widgets. This allows you to choose the widgets or content that is displayed on the contestants pages.
Each Widget has it's own settings where you can choose to view the Contest Category Title, Author, Photo and the Number of Contestants to show from a particular contest.
You can also turn the sidebar on and off in the the Contest > Settings Tab. This allows your contestants pages to be viewed in full screen.
