I never got notified that this answer of mine has been deleted. (I don't really care about it anymore, since the issue is resolved, but it added something to the discussion that was not present before). I realized it due to new activity on the post:
I couldn't find @random on the chat. So, I would like to add a comment on my own post to explain why my post was an answer, but I can't.
As of now, it is possible to edit those posts, but not to comment on it (for example to ping a mod that deleted an answer without a note and without an obvious reason, so he can see my explanations).
Would it be possible to also allow one to comment on their own deleted post?
