Just one bug I found:
In the mooderror template:
Change this:
<a href="/vb/mood5.php?s=sessionhash[sessionhash]">Back</a>
to this:
<a href="/forums/mood5.php?s=$sessionhash[sessionhash]">Back</a>
I think there is a $ missing, and change the directory to whatever the forums directory is in, or else the back link won't work. Which is not a big problem, but just wanted to point it out.
