So JD, if you submit these older pieces they will land further down the archive according to original publication date so they won’t be seen by very many people, if indeed at all. what you can do is copy the story verbatim and submit as new to Storymaker, then make the original “unlisted”. (Edit story > manage unlisted setting >make unlisted). This will not remove the original and will avoid a 404 error. It’s also acceptable under Medium rules to the best of my knowledge. I have done this with some of my own stories.
