Is what I did here appropriate? The question is somewhat old, but I came across it in Google results, and the accepted answer was just as wrong then as it is now. Since I got somewhat derailed by this I decided to add a better-quality answer after doing some research on the topic.
I understand it's possible to edit other user's answers, and as I mentioned in mine there was another that got the kernel of the answer right but provided no explanation, and in any case that answer was not marked as correct. It seems a bit odd for me to provide my answer in the form of an edit to this one-line response when nearly all the content would be new research, am I off base in that?
My intention here is just to have correct info out there for future googlers. Would it be better to create a new question? The system in question has not changed in several years so the answer would be no different then or now.
