Category, subforum category

[we_are_borg]

I have setup a forum but i have one thing i would like to see changed.

I make a category in that category comes a forum, this is all normal. But now i do a extra step namly in de forum i create sub-forums. This works great but the forum i created there you can post, now i tell the system no posting allowed that works great to but what i would like to see is that there is nothing there.

Don't know what i mean take a look here http://www.breedbandforum.com/forum/
Access the forum "Glasvezel Providers"

Now you see the sub-forums;
Concepts ICT Fiber & Wireless BV
Ons Net Nuenen

but beneth that there is
Threads in Forum: Glasvezel Providers
I wish to tell the system that on one forum it's not nesseccery and on the other it's needed.

Is there so sort of hack, if not can some one make it.
