Just a quick note to the forum admin and/or Foofy.
I highly suggest you download the .js file from wowhead and host it on your site rather than having each user pull it down from wowhead.com when the page loads in their browser.
I have been running my guild's website and forum forever, and we had numerous occasions where wowhead.com would be down or slow and because my users are pulling the .js from wowhead, their browser would stall or quit entirely before loading any of my site's content.
The down-side to this is that if wowhead changes anything, it might break and you need to refresh the .js file on your server. I've been running like this for at least six months now and haven't had any problems.
Oh, and mmo-champion now has their own item database and a .js file available so you can do the same thing with their items.
