You are probably referring to the one that used to be on GeorgeS' website. He relocated his site and the path to those tutorials doesn't work anymore on the new host. It should be easy for him to fix, but he would need to be aware of the issue. I will move this thread to his section of the forums so he can find it easier.
His tools are now located here:
http://www.georgestools.chrsschb.com/
And the link on that page for the Tutorials I believe you are looking for is here:
http://www.georgestools.chrsschb.com...tut/index.html
But that is a 404 error when going to that link, so I assume the folder is not there on the new host.
