How to center the Navagation Bar

[XPSuedoX]

Hi,

I would like to center my Navigation Bar on my forums as my Nav Tabs are on the left and all that I can do is change that to the right, but no center option in the code.

I have looked all over and found nothing and was hoping someone here may have a snippet of code to add in to the css_additional.css section or help explain to me how to fix this problem.

Here is a site that has the navbar centered ---> http://www.empirisoft.com/support/
