When I create a new page the sidebar appears which I don't want. Instead, I want the new pages to look like my category pages. Can someone please help me with this? I would normally have no problem figuring this out with a regular theme, but I am using the Gallery theme by Chris Wallace for Thematic, so that is causing a bit of confusion.
Here is a category page: http://gimmeatee.com/category/funny-tees/
And here is the page with the sidebar: http://gimmeatee.com/wishlist/
