The Network Admin Screen is the central access point to the various options necessary to administer the Multisite (or Network) capabilities of WordPress. The information below is directed specifically for Network Administrators. Other users should see Administration Screens for information on using WordPress.
The Network Admin link is only visible after you Create A Network. The menu will appear in the upper right of the menu bar, and is only visible to super admins. It has been moved to a separate location with the admin area, and is available from the admin area of any site, as long as you are logged in as the super admin user.
When visiting Network Admin you will see the Dashboard screen. This looks similar to a site dashboard, with one additional widget, and the site specific widgets removed. The Right Now widget has quick links to the Create a Site and Create a User screens, as well as search boxes to quickly find sites and users.
