My "account" says I have asked no questions, but I'm specifically asking about the question I asked to the Statistics board, which was moved to SO.
I initially was able to comment on a comment to the question. This is the expected behavior. I can no longer comment on that "chain", nor can I comment on a proposed Answer that does not work. I can only check Feedback if it is Useful Y/N, or edit the Question/Answer. I tried to Edit the Answer, but this was apparently rejected. I don't know why, and cannot make use of the site without knowing the "rules".
Am I supposed to join in a discussion (a chain of comments) to the Original question and proposed answers or am I supposed to serially modify (Edit) the Question and Answers to add the information?
