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)

eRate - rate posts!
A small, AJAX-enabled modification which allows your members to rate posts, trying to eliminate one-worded replies.

This little baby adds post ratings to your forums which allows users to rate each post.
It's all AJAX powered and uses the intergrated IPB handler so you don't need to worry about load times, just click and rate!

This mod will add it's self (when installed correctly) to every users profile, the bottom of every post, new column on every forum view and a icon against each username within a post.
