This folder in your path in your code:
/ widgets / index / templates / embed /
This leads to where you can edit the header, footer and other elements. Doesn't change the overall layout, but manipulates portions of it.
I'm sure if you poke around that area long enough you should be able to locate the layout file. (There are some folders in the templates folder that could lead you there if you know what you're looking for).
Hi Joshua - you can also kinda sorta cheat and use CSS, making the left column invisible by using { display:none; } and stretching out the middle column to make up for the left space.
how do you change the width of the second column? i made the first column disappear with the code you gave above, but now i'm left with a gap between column 2 and i guess column 3 (?). =P
