For what it's worth; I don't know what caused 38ac to leave, but I am certainly saddened that he has left.
I for one, have benefited greatly from his knowledge and input, and I am very thankful that I had the privilege of access to his posts at the time that I was working on my 6/1 clone.
I am sure that it turned out much better than if I had worked it over on my own, and now I have the confidence to tackle my other clones whenever the urge strikes.
