Don't fret too much over the matter, Drew. You are not being singled out. It has been the procedure on this site, and many others with the same format, for a long time. Not really a good test, but, you will find if you look back at your earlier posts you will find you cannot edit them. It makes sense. If readers have absorbed the contents of one of your older posts, and you then return and edit out mistakes, it rather negates the original help and contents of that particular post??
