yes i use it, and it looks like that cat that you got it from didnt do it right... he got it from one of my sites (hense the submitool link at the top which is mine) but decided to take all the multi-level ones which were before him out and put all his in...
i have used it for years and its pretty amazing how many folks have my links on their sites now so i can only imagion how many the folks above me have by this time LOL
if you want to keep it pure then i would suggest going to the source which doesnt have all the older links replaced at
