You ALWAYS search to make sure that someone hasn't already done your tutorial, so that you aren't wasting your time. The Hive really doesn't have any use for multiple tutorials of the same thing as far as I know...
Your tutorial is about as detailed as Ralle's, and since has been around for more than a year, and the fact that he's the chief admin, I think his wins.
If you were willing to cover a tutorial area that has not already been done (make sure you search first) then go right ahead! Make sure to be as detailed as possible, and to include screens if you can.
