Your post came across as criticizing by saying nothing more than "staggering". As I am often criticized for the length of my posts, without any other clues in yours, I was unable to tell your comment apart from those who are saying the length is a bad thing. It said nothing about appreciating the subject or the effort. This comment does explain better, thank you.

I try not to delete comments unless they are spam or unless it has devolved into a flame war where the commenter is really doing nothing but ad hominem attacks.
