Three-Column Page

If anyone knows how to make a smooth transition over to a three-column face for this place, please contact me; it’s what I’ve been trying to do and failing to figure out. Unlike TypePad, there seems no proper and simple way to set up Blogger in this manner and I think I'm really screwing with my Template. Should you see 'static' here over the next little while, please know it's just me playing (and failing!).
