The complete description of JvB Bridge can be found here. This is a back-end component only, so you can see all the settings once you login to the administrator demo.

The description of the module vBulletin Latest Posts can be found here. You can see the module which shows the list of the latest posts from different forum threads which are shown as tabs. Please notice that module should be placed in a wide horizontal position.The bridge works in the way which allows not to create menu items with links to forum, not to wrap forum in Joomla (but you can do it if you want with the help of native Wrapper component). You just install the bridge, configure it and have a bridged Joomla and vBulletin. This means that you'll have same users in both systems and if user logs in Joomla, he will be logged in vBulletin.
