How do I Adjust Subforums Columns?

[greygaming]

When I go to a site like Steam Example who has their Game Discussion section subforumed in 3 columns. By default the Subforums only seem to show 2 columns in vB 5. I want to know how to adjust the number of columns.

In addtion if you click on the Category that has subforums and go to its main page (Steam Example 2) they are still columned, but when I do that on my site using vB 5 they are listed like standard Forums. How do I accomplish this columning on this page as well.

When I search how to do these things I find walkthroughs that work with vB3 and vB4, but it would seem the method is different for vB5 as after step 2, there is no more options with names equal or simpilar to what they say to choose.
