After you create an article and make it public (green circle: Save and make public) you will be able to see its green timestamp in the articles table. Click on the timestamp will open the article in new tab. By clicking on the copy icon you will be able to get its unregistered url address. Use that url only for preview or if you don't want to follow its results.

If you want to copy registered article url address you will need to see its registrations by clicking on the 🔎 icon which will result in the registrations table where you can see their details.

Click on the table row for the registration you want the url address for and it will take you to its Hosting view table with results icon and other icons. One of icons is a copy icon under Actions column.

Click on that icon in order to get the full article url address with all registration details included.

By using the registered url address you (and the Hoster you have made deal with) will be able to follow its results.
