Hiding left column altogether?

Hello,
I'm customizing ZC to match the look of my site, after a whole night of try-outs I finally managed to match the css and header and footer.

I have disabled all the boxes that appears in the left coulmn (where by default you have the Information/Catagories etc. ) but now I still have that blank coulmn that I need to get rid of.

I tried editing column_left.php but being a n00b I messed the whole thing.

anyone knows how can I keep just the center and right column boxes?

thanks in advance for any reply.

To turn off the Left or Right Column ... peek in the Layout Settings and change the setting there ...

well I think I tried that:

Still I'm having the column in there, it's empty, but it's there.

in admin -> configuration-> layout settings
turn left column OFF globally

OMG I feel so stupid :)

thanks for the help.
