oh, hehe, english ain't my native languageApart from the grammatical fix in your quote , please note that Rawr 3 which is at the Elitist Jerks hosted link you mentioned, uses EXACTLY the same calculation code as Rawr2. The ONLY things that are different is the user interface components ie: the look and feel and the fact it runs in a browser.
