This answer applies to Yahoo! Domains, Custom Mailbox and Business Mail.
When you signed up for your service, we automatically created a placeholder "Under Construction" page for you at your web address. You can replace this default page by creating a customized page of your own (also called a starter web page). With a starter web page, you can enter your contact information into one of our templates to create an attractive, professional welcome to your visitors until you're ready to build a full web site. View a sample.
To build your starter web page:
Please note: The starter web page is not a full web site, so you will not be able to add pages, alter our templates, or add your own images or HTML. To fully customize your web presence, you'll want to upgrade to Yahoo! Web Hosting.
You can also divert your site visitors from your "Under Construction" page by forwarding your domain to another web site you specify. Visitors to your web address will not see your placeholder page; instead they will see the page where you have forwarded your domain. Learn more about domain forwards.
