Annie, don’t worry, it’s okay. On the PC, pull up “Mouse” again, click the Edit button in the top right, which changes to Publish. Next to Publish are three dots … — when you click on the three dots, you’ll see Add to publication, click on that. Now you have all the publications you can publish to. Just select The Junction, and you’re done!
And it will be as if it all never happened.
Sadly, as messed up as the whole publications thing is (you missed some of the editors complaining!) it’s not even on the top 5 Messed Up Things On Medium.
