I had not responded to this question because the truth is, we do not know. Help center fails to mention anything about stories that are not accepted into the publication and the test draft I made for S Lynn Knight to reject, notified her I would get a notification, but I didn’t get one. Maybe because I am a editor for the publication. I hope people did get the notifications Medium promised.
While on this topic, I want to stress that we had to pass on a lot of stories that were very well written and a lot of fun to read, but just didn’t use the prompt as explained in the guidelines.
