Just to see about getting more info on this plugin I did a search for it on Google, and got a very strange results page. After #2, it was almost all links that pointed to the cystats directory inside of sites using the plugin...check it out:

Something's not right there...I don't like the idea of putting the guts of a website on SERPs.
