How do I keep my logo in the same spot?

Hi, I was wondering how you keep your top logo in the same spot on every page?

Right now it lines up with the main content boxes of the site but some pages like Forum are not centered which pushes the logo all the way to the left. Is there a way to keep the logo in the same spot? Or center the pages like Forum?

I found a post called "Centered Forum" but it said I couldn't access it. I just paid for a premium membership but still can't get into that forum. Can someone help me out here.

Thank you.

I kept mine on the LEFT hand side, so it's consistent on every page.

I am not 100% sure, but i would look into the header file in   ../templates/base/_header.html ;
