I've been working on highlighting Admin comments on my wiki and I have a few questions. How do I highlight the root post like on this blog? Here's my Wikia.css. Also, can this be applied to user message walls? Article comments are not enabled on the wiki. Thanks.

Edit: Okay, the problem is just with one of the Admins: SJ4evr.
