Changing the background of the blog
 

I have the vBulletin Blog plugin. It's great. When I installed it, for the most part, it did a fine job of incorporating my existing style. However, there's a lot of dead white space. After some success messing with the CSS of vBulletin itself, I was confident I could go to "Edit Templates" and quickly find the errant location and plug in the right background. This hasn't been the case. The blog doesn't show up on the Main CSS panel with the rest of the vBulletin CSS. I'm thinking under "Blog Templates", that "Blog" is the list of CSS definitions, but I'm probably wrong. I don't know where to begin.

I'll link to a couple screenshots to better explain my problem. I circled the problem in red. I have a feeling the same code would fix my entire problem, but I'll post three different pages in the hopes it clarifies the problem. Thanks in advance for any help anyone can offer. I'm trying to learn everything about CSS and vbulletin but I'm not learning fast enough. http://www.buchisdma.com/forums/blog.php
