The one I usually post is attributed to FReeper FireHat. I do sometimes post other versions. I have a copy of several versions of it. I do not know which is the "original". If you and section9 say the one you posted is the original I'll take your word for it.
No, bad wording on my part. I just meant that I had bookmarked Section9's ultimate flame cuz' I thought it was great. I didn't see originally that yours has many of the same phrases, and since we don't have an edit function, I was stuck. I did find this website when I googled for it: www.ultimateflame.com
