When you click on the categories within my site, it takes you to a page with the excerps, which is fine...My problem is that the excerpts take up only half of the center colum. How do I make them take up the whole center colum and not look like they are stacked on top of each other. The website is: http://www.LaptopsandLaundry.com

Thank you!

You have the right inner sidebar turned on for that page type, see Theme Options -> Style & configure SIDEBARS -> RIGHT INNER sidebar: Display on:

It worked...Thank You!!!
