How do I remove my site name from the title tag?
The CMS now allows you to choose whether or not your site name
prepends the page name in the <title> tag. To
change this setting, go to Manage Content > Page Defaults and
then select the Browser Title checkbox.
If your website was created before June 10, 2009 and you are
having trouble getting the site name to remove itself from the
<title> tag after publishing, you will need to
open and resave each template in use by your site. This will force
the new title to adhere to the checkbox setting you've
selected.
