I regreat to say that the Jet Doctors web site is now down. I for one found his tutorials very useful. There fore I decided to contact him to see if I could reproduce them on my web site.
I'm glad to say that he not only agreed, but sent the files to me as well. You can find them on my site just follow the link below.
I hope you find the tutorials as useful as I have.
