how the hell did you do that.

Ok, so first you will make your main category in forum manager.... this will make it not viewable on forumhome...

Main Cat:

Act as Forum --> NO
Forum is Active --> NO
Forum is Open --> NO

Now your sub cats which will be viewable in Main Cat...

Cat:

Act as Forum --> NO
Forum is Active --> YES
Forum is Open --> NO

Then your forums...

Forum, also viewable:

Act as Forum --> YES
Forum is Active --> YES
Forum is Open --> YES

That should do it...
