Using the navigation bar on top of your Yat dashboard, click the Yativerse option on the right! This will bring you to the old Yat dashboard page where you can edit and create an old-school Yat page!
Please note that your Yat username will only use The New Yat page. Any old Yat page or redirect associated with the Yat will be disabled. If you see an error message & would like to create an old-style Yat page, simply change the Yat username. Also note, if you only own a single Yat, you will be asked to switch to The New Yat page which will disable any old Yat page or redirect associated with it. You will see a warning message before switching over.
