Hi Chris, it's super easy to copy a Medium story and paste it into your Substack. The editor is pretty same es Medium's. Clean and easy to use. My recommendation is to share unique content BUT you can also republish your most successful stories there (or the other way round). Substack can be a tool to amplify your reach! My tip, just give it a try. It's super easy to start. If you need any help, just leave a comment. I promised to soon share further details about starting a Substack and promoting it etc. Hope this helps. Have a nice weekend👍
