I'm using an old, extremely modified version of Atahualpa (version 2.21 -- yikes!) on a non-profit site. Now they want me to build a new sister site and, of course, my first consideration for themes is Atahualpa.

Anyhow, onto my question... with the newest, greatest Atahualpa: is it possible to turn off sidebars on all subpages or designate which pages to not have them display? Or is it a matter of writing a new page template and excluding the sidebars via code?
Many thanks in advance!
