How to change your site name in Drupal 7
The Site Name in Drupal 7 is the main title that your visitors see on your page as well as well as the the title shown in the upper tabs of your visitor's browsers. It is located in the header portion of the page and is written in the largest text. By default, the site name is set to the domain name of the site. You may not want to show that as your site name, but change it to something else instead. For example, your sitename may be catsanddogs.com but you want to display Cats and Dogs as your site name. Editing the site name in the Drupal 7 admin dashboard is very simple once you know how.
