I posted a comment on this answer which answered a question posed in a comment by the OP. Could the person who deleted this comment please explain why it was deleted (and post it here so that I do not have to retype it yet again).
As a non-mod I do not know how much work is it to find the problem and edit such comment. (As I never had an opportunity to edit comment of another user.)
So if some of the moderators feels like this would be useful, you might consider editing it.
I am not sure to which extent this might be useful. (The question is quite old.) But I mentioned to the user who posted that comment what the cause of the problem might be: math.stackexchange.com/questions/930252/…
@BillDubuque From what I can see, your comment did not answer the general question posed in this comment. It basically pointed the asker to your answer, and set off a chain of off-topic, non-constructive comments, since deleted.
@MartinSleziak Fixed. It's often not hard to appropriately edit such comments. Copy the course into an answer box, check to make sure that the basic MathJax isn't causing errors, and insert a space or two or three, and then copy that into the comment.
If the comments is removed, so should probably be the whole conversation following it (and discussing why it was rendered).
Maybe it would be useful to leave that conversation there at least for some time, so that the poster of the comment gets my ping pointing him to the post on meta.
@MartinSleziak I might just leave the original comment there, so that your ping will get through, and then try to come back later to clean it up. (Do you mind if I edit your comment to request that it be flagged as obsolete once read by flawr?)
@ArthurFischer Or if you prefer, you can remove my comment and replace it by a new one - mentioning that you have edited the post. (So that flawr is not surprised that his comment is correctly rendered now.)
