Welcome to Medium, and thank you for following me. You are absolutely right: There is "no wrong or right way" to write. But I'd argue that, while there is no right or wrong way to impart information or express your feelings, there is a right way to do that stuff your English composition teacher wanted you to do--even though she may have been telling you what's wrong when she should have been telling you what's right. So:

Send me your next two stories/articles, and I'll edit them for you for free. Just the grammar stuff. I won't touch the more important part--the content.

Do you know how to send a draft to somebody? In edit mode, a "Share draft link" option is accessible through those three dots to the right of a story.

Good luck on Medium.
