Domain forwarding — available only to Yahoo! Domains and Business Email customers — lets you point your domain name to another home page or web site location. Forwarding is handy when you have a web site built elsewhere and you want to give people an easy-to-remember domain name to reach your site.

Here's an example. You can forward:
http://www.widgetdesigns.com/    http://geocities.yahoo.com/widgetdesigns/

So when people type http://www.widgetdesigns.com/ in their browsers, they'll see http://geocities.yahoo.com/widgetdesigns.

Note: Advanced users may also take advantage of advanced DNS settings (A records, MX records, and CNAME).
