Grafter on "Change MagicBlue theme to one column - how?"

Hello

I'm very much a fan of the 'MagicBlue' theme.

The problem is its 2 columns, and I really only want one column. While I've managed to hack the CSS code to get the width of the first column to extend the full width, I can't get rid of the original vertical blue line that separated the two columns.

Any help warmly appreciated!

Thanks in advance!
