Online resources to learn Flight Simulator 2004? (and basics of how to fly?)

I had another thread asking whats the best way to learn Flight Simulator 2004, but now I have a slightly different question...Are there any good online resources that teach how to play Flight Simulator 2004? (eg. how to fly, all the basics, etc)Of course the actual FS2004 CD's have the whole Learning Center, but I'm looking for something I can read while I'm here at work.Thanks for any suggestions!
