I found this on the internet while doing a google search on normalizing, I thought it was quite interesting and might clear up some questions beginners have. http://www.youtube.com/watch?v=3_BH6HqpPtk

Woodyb that is about as clear as it can be put. Thanks.

Indeed thank you Woody. Reminds me of Navy training films.

That really covers it well. Thanks for finding and posting that one.

Can't believe that was my fist post. Guess I'm more of a reader than a writer. I've been enjoying this forum for some time.
