Due to the fact I no longer feel the desire to maintain and update tutorials as required, I have decided to remove all tutorials from my site. Much of the Blender related tutorials are already somewhat out of date.
As of Monday morning I will be deleting the tutorials pages completely.
If you still find the information on them useful, then I highly suggest you make backups, the videos on Youtube are already unlisted (you can still access them from the tutorial pages should you want to bookmark them).
Once they are gone they are gone.
