barc00de, Choose Design #121, I will show you how you can change it to the Design #111 and at the same time have %100 width. Go to CP » Customize design » Page Editor » Site pages
And remove:
Code
<td width="195" valign="top" align="right">
$GLOBAL_DRIGHTER$
</td>
Do the same thing in every module. You can move $GLOBAL_DRIGHTER$ under $GLOBAL_CLEFTER$
so that you can have all of the blocks on one side(left).
See how easy that was, but if we were to show you how to do that from 111 design, that would be hellava work.
