Good article, but why a damn PDF format!
First off, when Adobe AR came up..up popped a notice that a security update is necessary...so, I allowed that. Then, when I could get back to the artical..the reading is so long in the tooth (about page 12 to 14 before the "meat" is presented) that I have forgotten what it said leading up to it..and had to go back and re-read (old age & memory problems).
I just saved it and will copy to a text file, closer spaced where more of it can be read on one page before moving on.
