vBulletin LTS

Go to your navbar template
(AdminCp -> Styles & Templates -> Edit Templates -> navbar)

At the top, you will see a <br />. Ok, below you have to add all this code (that's the complete modification code):

Code:

(Remember to check the red code if you want change the text to fit your needs)

Now if you save, you will have two navbars. Then, you need to remove the default vBulletin navbar code. Basically, it starts with this comment:

Code:

<!-- breadcrumb, login, pm info -->

.. and ends with this one:

Code:

<!-- / nav buttons bar -->

You need to remove all the code inside these two tags.
Now, what do you need? Three images. You must upload them in your style folder called misc (yourforum/images/misc):

• &stc=1&d=1196698072
• &stc=1&d=1196698072
