Need help with forum structur and templates

[Kyo-dono]

Hi.

I want create a structure like this (in 4.2.0):

Select Language (Category)
- - English Forum (Category)
- - - - Forum BB (Forum)
- - - - Forum AA (Forum)
- - - - - - Sub-Forum AAA1 (Forum)
- - - - - - Sub-Forum AAA2 (Forum)
- - German Forum (Category)
- - - - Forum CC (Forum)

The problem in vBulletin4 is, its not possible with category in category.

forum.php look like this:

There is a topic in "Forum BB", but vBulletin shows here nothing. Its okay for me, but the headline with "Threads / Posts" + "Last Post" doesn't belong there. How can I remove it there? So I wish there is no listing of sub-forums under this category too.


Now I click on "English Forum" and get this:

Here are a lot of errors.
1. I read "Forum: English Forum". But "English Forum" is a category! I want remove "Forum: " here.

2. In the headline you read "Sub-Forums", but it should be only "Forums".

3. The "Sub-Forum AAA1" and "Sub-Forum AAA2" should look like that:

Can anybody help me here, please?
