full width on text

Hi.

I have a cosmetic problem. I’m using the Semiologic, 3 columns 3.2 theme, but I’m not using the middle column. Instead I want the first column to have the extra width. It only seems to be possible to change the width of the sidebar (right). Though changing the size of the textarea for comment also adjusts the width of the post above it. My wish is for page, where comments are not allowed, to be shown in the full width too.
