Forum Replicate the home page for this forum
 

I am trying to replicate the method of organizing my forum in the same way as the home page for this forum.
http://www.vbulletin.com/forum/forum.php

Specifically I will refer to the top of the forum:

VBulletin Announcements (Category?)
VBulletin Announcements (Forum)
vBulletin Announcements Find out the latest news about vBulletin here
vBulletin Developer Chat Forum (Forum)
This is the place for the monthly Developer Chats

When I click on the top category:

VBulletin Announcements (Category?)
I am taken to another page where the two forums are listed under the category of Sub-Forums:
http://www.vbulletin.com/forum/forum...-Announcements

Sub-Forums
Bulletin Announcements (Forum)
vBulletin Announcements Find out the latest news about vBulletin here
vBulletin Developer Chat Forum (Forum)
This is the place for the monthly Developer Chats

I cannot seem to figure out how this has been set up.
My forum is not yet commissioned but can be found here:
http://audioforbooks.com/wordpress/forums/forum.php

I am brand new to VBulletin and have the current version 4
Thanks for any help

Pete
