Can you describe where you are in the hub publishing process? There should be no need for you to re enter anything, as no confirmation is sent when you publish a hub.
On the top menu press the button "Start a hub" and then follow the instructions as they appear on screen. When you are happy with the contents you have three option buttons "Preview", "Publish now" and "Done Editing".
"Done editing" saves the draft for next time but doesn't start the publish process. If this is where your are then you need to go back into "edit" and then press "Publish now" button.
Under your account you will then see the hub listed as published but "pending". This means it is undergoing review to check that it meets the quality standard. After a few hours (hopefully) the status will change to "featured" and then everyone will be able to see it and your ads will appear on the hub.
