Blue Citron actually provides two themes, one fixed width and one fluid width. I always build themes like this so that you can use the fluid width version for the admin areas of the site.
It also changes the CSS for the Jquerymenu module a little to make the theme match (if you happen to be using that module).
I can be contacted for customizations of this theme or for other projects through my contact form or at www.PixelClever.com.
PS: This theme is for Drupal 6 only and will not be backported.
