I'd like to go with what saline said in the fact that it is currently almost invisible. On the forum home I would place it just above the footer and right below the Private Messages and Who's Online. Why? People tend to check to see who's online (esp. guests -- they like to see how active a forum is) as well as their private messages. To add onto that, where it is right now on the forum home seems a bit, "mis-placed", perhaps. While not having it at the top makes it not as noticeable right away, but it could be more noticeable when it's closer to something people look at.
On the forum display, show thread, and reply pages, I would actually make it center above the links, "Code Newbie Forums > Category Name > Thread Name > Thread".
Just my feedback.
