There is no approval process on sign ups - they are published immediately. Therefore, if the status of your sign up is listed as "Draft" on your dashboard, this simply means that you haven't yet completed all the steps to bring your sign up live. Click on the orange text reading Edit sign up next to the name of your sign up and then make sure you complete the final steps to bring the sign up live. When you are finished, you will receive a confirmation screen that tells you the web address of your live sign up.
