I created a website when first signed up. Now I have created a better website to replace the old one. How can I delete the old one and replace it with the new one?
Just use the "Publish" command. You can find this in the drop-down menu, which you can open in the main Website Maker editing screen by pressing on the downwards arrow in the uper left-hand corner. This will take the site you're currently working on in the editor and make it available online, so that people visiting your URL will see it.
