No. The tools in your Yahoo! 360° account allow you to make your blog unavailable to the public; however, if you change this setting, your blog will no longer appear on your web site.
If you have accidentally used the tools in your Yahoo! 360° account to change your blog setting to private or viewable by friends only, and you want to continue to view your blog on your site, visit your Yahoo! 360° account, click the "Edit Blog Settings" link, and, under "Who can see your blog," choose "Public."
Tip: If you'd like to limit access to the blog on your web site, you might consider setting up password protection. Move your blog to a subdirectory of your site, then password-protect that directory, and provide user accounts only to friends or colleagues to whom you want to grant access to your content. (Please note, however, that the blog in your Yahoo! 360° account will remain public.) Learn how to set up password protection.
