The Yahoo! Site Wizard allows you to create up to five pages for your free web site. If you've previously removed one of these pages by clicking "No" under the question "Include this page in my site," you can re-enable the page anytime by reopening the wizard, returning to the page you removed, and choosing "Yes" instead. (Please note that the home page cannot be disabled.) After you enter new content for that page, just republish your site to save your changes.
To create more than five pages, and to take advantage of more sophisticated design and editing features, consider upgrading to a Yahoo! Web Hosting plan and editing your pages with a more powerful site-building tool, such as Yahoo! SiteBuilder or Yahoo! PageBuilder.
