Is their an "official" flixel guide or set of video tutorials for folks to learn all about how to use Flixel?

I believe I have a good enough handle on how to use Flixel but wanted to know if there was a guide or video tutorial set that you can point me to so I can read up on Flixel and it's features (how to use them) in case I missed something. I already scoured YouTube and seen what you have posted there.

Thank you.
