That one's actually a pretty easy fix:

<span style="color: blue;"><p style="text-align: left;">425&gt; <strong><a title="BH: Return faceplate with EXTREME Prejudice" href="?p=3733"><span style="color: blue;">BH: Return faceplate with <span style="color: red;">EXTREME</span> Prejudice</span></a></strong></p></span>

The stuff I bolded is the "title" of the link, a.k.a. what pops up when you mouse over it. Putting tags there breaks the code. As far as I know, you can't change the text style/color of that text. What I underlined is what the actual link shows up as, which is where you put the tags to change the look of it.

Also: Holy crap you've done a lot of work!
