etuitions, the plugin is designed to act only as a reference for LaTeX commands - that is, it only integrates a LaTeX command reference with the vBulletin post editor. You'll need to setup your forum to process LaTeX separately - this involves implementing a couple of Hooks in vBulletin that intercept the posted message, parse out the LaTeX, run the LaTeX through a LaTeX rendering executable (such as MimeTeX and MikTeX if you have a Windows server, or the standard Linux LaTeX packages if you have a Linux server) and finally replace the LaTeX code with the generated images.

You'll need to be familiar with PHP to implement this. I realize that the whole process of setting up your forum with LaTeX can be simplified with a vBulletin plugin and i have been working on such a plugin and it should be completed in the coming weeks. Meanwhile, since you seem to be in a rush, have a developer look at MimeTex and the vBulletin hooks.
