Bill, I would just like to pass on my kudos for your great tutorials. I have been following your site since it started and have learned much already.
I follow other forums as well for "tips" and "how to's" and all are helpful and appreciated.
The difference I am finding with your site though is that you include the thought process that one might go through when trying to understand the logic of a certain task. While lots of other generous contributors on various sites offer up advice or answers to questions it is often outlining the commands to use or identifying where to find stuff, but it doesn't usually include the thinking process behind the "why do we do it this way or that way" ?
You do and it really helps to crystalize my understanding of the subject task at hand !
So keep up the great work !
