Making forum skin 100% width

[LoOnEyToOnZ]

Hello, my forums is at www.sgwhz.com

Any idea how i can make it 100% ? Cause would like it to be wider, so i can add a sidebar on the left hand side.....

Thanks !

its one of the first options in the style options.

Style width in percent or pixels

set it to 100%
