Site Name in the Titlebar
Administrators can change the the name of the site that appears in the titlebar on the Admin/Top Level Navigation Bar page.
Administrators can also enable or disable the "Email Support" link, change the text of the link, and set the email address.
The email link is a "mailto:" link. Clicking on it will open a new mail message on the user's computer addressed to the email address configured on this tab. This assumes the user's browser is properly configured to handle "mailto:" links.
