By twin column you mean a column on each side of the main content being displayed correct? I have a test site of vbulletin , latest release installed at www.new.brotherhoodofgamers.com and there is already 2 columns on each side, although I might be wrong and not understand correctly what you mean by twin columns.

And the vbulletin one only shows the columns on the homepage?

so we have to manually edit the templates to post the content?

Any way to make the columns a tad bit wider? maybe 170px, I edited the css but it did not change, maybe I did it wrong.

You have to change all instances of "135px" to the width you want in the CSS.

.

I did change them all to 170 but I still get this http://dixietalk.com/forum.php

So what about this?

Yes.

Columns are 170px.
How wide are your ads ... if they are 170px you need to make then approx 15 px wider, to allow for padding.

And would this interfere with the vbulletin CMS?

What would one need to edit to get the boxes to come exactly inline with the Main Catagory section?

Plus, i'd want the yellow bar at the top to go over the boxes too, can this be done?

(see attached mockup)

Welcome message will cause problem and if you manage to sort this out then other forum pages will not align properly.

Try adding "{vb:raw ss_twincolumns_start}" to the last line of navbar template and you will see what I mean.
