Sub-Categories

[1stsAz]

I am new to vBulletin but I am trying to set up my board to have categories, forums and sub-forums but in some cases I want a forum to act more like a sub-category rather than a forum since I don't want users to start posting threads in there. I can disable posting but it still shows a list of threads.

For example, if our gaming clan wanted to create a forum for a tournament, we try something like this:

Tournament Name ->category
Muster Area {this is a forum (no posting and no thread listing - more of a sub-category)}
Axis {Sub-forum (posting and thread listing)}
Allies {Sub-forum (posting and thread listing)}

I've uploaded Sorky's Subforum list control but as a newbie, I am finding it difficult understanding what each thing does and I can't find any user manual or documentation explaining each thing.

Any help would be greatly appreciated.

Thanks in advance!
