A NULL Story
Why? Because the only way to get to it is to publish a story, which I did yesterday, and was given the prompt to create my new URL. But I happened to click on the “learn more…” link at the bottom of the page to see what was going on here at Medium… and…
…And then Medium would not allow me to return to the page to set the URL!
After talking to support, they informed me that I will only get that page when I publish a story. So then, here’s a story simply for the purpose of accessing the tool to convert my legacy account’s URL.
I’ll leave this little story up, in case someone else with a legacy account has a similar question.
