After reading Suggested edits that add an answer to the question, linked in the comments was a suggested edit that was rejected. I thought I'd leave a comment to the new user who suggested it so they would know what happened, why the edit was rejected, and how to ask a new question:
@OFG: Your suggested edit was rejected because it really is another question and doesn't improve this answer. Use the
AskQuestionbutton to ask a new question. Feel free to include a
linkto this answer if it helps others understand your new question.
But I don't think the @ ping will work, since that user is not in the edit history as an editor. Are users that make suggested edits valid targets of @pinging from that post in the same way editors of the post are?
