Hmm, I misread that LD. No, it's not for sub-
forums, but sub-categories.
It allows you to add a category inside another category. Each category can contain both sub categories and forums, or one or the other. The same goes for every sub category - they can each contain more sub categories, as well as forums. It is infinite in the sense that you can have something like this.
Main Category
Forum 1 (is in Main Category)
Sub Cat1 (is in Main Category)
Forum 2 (is in Sub Cat1)
Sub Cat2 (is in Main Category)
Sub Cat3 (is in Sub Cat2)
Forum 3 (is in Sub Cat3)
Sub Cat4 (is in Sub Cat3)
and so on for however deep you want to go. Is that a better explanation?
