When you downloaded SiteBuilder, you installed the SiteBuilder tools on your own computer, just like any other program you might use regularly, such as an email client or your word processing software. You can open SiteBuilder again from your computer by finding and clicking on the SiteBuilder start button, a small image that works as a shortcut to your tools.
The first place to check is your computer's desktop: When you find an image like the one at right, just double-click on it (click on it twice quickly with your mouse) to open SiteBuilder.

If you can't find the shortcut on your desktop, don't worry! You can also start SiteBuilder from the SiteBuilder folder that was created when you downloaded your tools. On your PC, click the "Start" menu (usually located in the lower-left corner of your screen) and choose "Programs." Select "Yahoo!," then "SiteBuilder." You'll see an icon like the one above labeled "SiteBuilder." Select this option to open SiteBuilder.
If you still can't find the SiteBuilder icon, try using your computer's search tools to find it (search for SiteBuilder). If that doesn't work, go ahead and download again!
Remember, because SiteBuilder is downloadable software, you'll need to install it on every computer you want to use to work on your site. In other words, if you started your site at work, and you want to continue working on it on your personal computer later, you'll need to download it again when you get home.
