I've been trying to switch my blog to a three-column format, based on black-letterhead. I've been trying for a few days but failed miserably :( Can anyone help? I've seen some sample three-column modifications to letterhead and blackletterhead but they were all MAIN-SIDEBAR1-SIDEBAR2 format. I want to have a SIDEBAR1-MAIN-SIDEBAR2 format. Any help would be greatly appreciated.
