seperation between categories on vbulletin

One of my sites has this setup, and I am thinking of changing it back to more of the stock look where they are all attached. I don't see any benefit to having the categories seperated, and it is probably just extra code that I can do without.

Question is, where would the code be? I didnt do the design, so I am not sure where to look.

Here's the info on how to do it, so it may help you back out the changes:

gap between forums - vBulletin Community Forum

its probably the $spacer. look in the templates for the spacer template and kill the margin or padding thats on it (i forget, i removed it as its more useless vBulletin code )

wow, alot of mess there just space a category. I will look at it real quick, and if nothing else, just re-insert the stock code, LOL

Dont try just replacing the forumhome template back to stock, it doesn't work, LOL.

There are three versions of this template hack. The one on vb.com, and two on vb.org.
