It took me long enough, but I finally got around to posting the first tutorial. It's a very basic tutorial, so if your looking for some advanced help, you won't find it in this one. I do plan to write some more advanced tutorials in the future though.
Remember, if you want, you can submit your own tutorials. I'll even clean them up for you, edit them, post the screenshots, etc.
Ok, here's that tutorial... enjoy!
