Aligning Sub Forums into columns

[Clydesdale]

Hello to all. I am an uber-newbie, and I am in need of some assistance.

I have searched and searched to find out how I can put my sub-forums into columns like this site;

http://www.scoobieforums.com/forum/index.php

I am running version 3.8.7

Thanks in advance for your help

3.x version here:

4.x version in case anyone has the same question or cannot find for 4.x:

There's other sub-forum managers so be sure to search for those but that one should do the trick ;).
