You didn't @ tag AOU, he might not see your request. (To note, adding a tagged person in an edit to a comment doesn't initiate the tagging, only the initial posting. Adding the @ now won't tag him and would need to make a new reply with the tag in it if you wanted to tag him.) Also, I believe you should be able to move it yourself via the options under your OP ('Move' button). You then type in/select the sub to move it to.
