How do I expand the width of my forums?

[SLGR]

Take a look at the picture attatched.
The yellow lines show the current width.
As the yellow arrows show, how can I expand the width some pixels more?

Admin CP -> Styles & Templates -> Style Manager -> StyleVars (in the menu) -> Spacer Size

Even I wished to do this to my forum, but I tried ur method by decreasin the spacer size from 25 to lower values, but the width or gap between the forum content and body corner did not decrease !

There is also the Main Table Width setting, as well as the body margins in this class:

Admin CP -> Styles & Templates -> Style Manager -> Main CSS (in the menu) -> Body

Thank you. Worked just like a charm.
