New Rating System? Options

look at this thread for an example

http://www.sacred-magick.org/index.php?showtopic=5235

I noticed that on the upper right corner of every post there is a tool bar that allows me to "rate" the post according to its content. Naturally I had to try it out. I clicked on a random rating then refreshed the thread. I saw a little icon on the left hand corner and a little tab that said list. When I clicked 'list' it gave the fatal error message. So my question, is this something thats just new and still has some kinks before it works right or what?

Apparently I'm artistic. At least thats what the little dodad to the right of my screen name implies. And ile, if you see this, you weren't confussing as the dodad next to your screen name suggests. It was just me tooling around without asking questions first. (IMG:style_emoticons/default/smile.gif)

It displays them for guests. Does that mean anyone can rate without registering & logging in?
Also, I find it a little annoying to have two extra things flanking either side of the top of a post... why not have 'em both on the same side? In their own column? Or running along the top?
