Is the current build of the forum module capable of something like this?

Forum Page

Maincontainer
------sub-container 1 (where topics can be created)
------sub-container 2 (where topics can be created)

Maincontainer2 (Another main container)
------sub-container 1 (where topics can be created)
------sub-container 2 (where topics can be created)
------sub-container 3 (where topics can be created)

Maincontainer3 (another main container)
------sub-container 1 (where topics can be created)
------sub-container 2 (where topics can be created)
------sub-container 3 (where topics can be created)

I've tried doing this using these:

A. Forum Page {set to ForumHolder}
ForumHolder
------Forum
------Forum2
ForumHolder2
------Forum
------Forum2
------Forum3
ForumHolder3
------Forum
------Forum2

But doesn't work. It seems like the ForumHolder is an actual page.

B. Forum Page {set to ForumHolder}

Forum
------Forum
------Forum2
Forum2
------Forum
------Forum2
------Forum3
Forum3
------Forum
------Forum2

Also tried this but can't get it to work.

------------------
By the way, by "Forum Page" I'm referring to the actual page that appears on the live site. So when you go to the Forum Page, you can see a page with Maincontainer, Maincontainer2 and Maincontainer3.
And clicking on "Maincontainer" will give you a page with the sub-containers. And so on...

I'm not sure if I'm making myself clear. Can the module make something like this?

Thanks for any clarifications.

And oh... SS is a real treat! Thanks.
