About Mathjax

[jackvb2013]

I'd like to ask where I have to insert the code described in this page

http://docs.mathjax.org/en/latest/platforms/index.html

in order to write LaTex in our vbulletin 4 forum.

the guidelines are "Most web-based content-management systems include a theme or template layer that determines how the pages look, and that loads information common to all pages. Such theme files provide one popular way to include MathJax in your web templates in the absence of MathJax-specific plugins for the system you are using. To take advantage of this approach, you will need access to your theme files..."

Where can I find this vbulletin file in order to paste the MathJax code?

Thanks
