STEP 1 (of 4): Your Site Title
Once you sign up for your new site, you'll be taken to a blank SiteBuilder page. This will be your Homepage.
At the very top is a message that says "click here to edit title." This is the placeholder for your site's title. Double-click the message to activate tools for editing your site title.
You can use the tools to format the style and font of your title. Use your mouse to drag the title into the right spot.
Click anywhere outside of the title editor when you're done. You're now ready to start formatting the main content of your Homepage.
