Kirupa's full flash site/no preloader

Okay here’s another preloader question. I am building my first flash site, so I’m using the tutorial based from the Kirupa Full Flash Site tutorial…
http://www.kirupa.com/developer/mx/full_site.htm
Only problem is, there’s nothing mentioned from what I can see regarding how to implement a preloader for this site. I’ve used some preloaders and nothing is seeming to work with this setup. Has anybody used this tut for their setup and inserted a preloader that works with this setup and how to do that?? Thanks.
