Dash (-) before Title on Each Joomla Page

Dash (-) is used in Joomla page titles to separate the Site Name and the Page Name. For example: "Our Company Site - About Us." If you happen to see pages as " - About Us", then this implies two things. One is that you have chosen to show the Site Name in the title on each page and that is why Joomla is putting the dash in the title; to separate the site and page name. Second, it implies that your site name was left blank. As a result you have the dash separating a blank space and the page name. Simply check your settings and give your site a name!
