The administration area of Elgg is reached by clicking on the Administration link in the topbar. You entered this area after completing the installation of Elgg. The primary page is a dashboard that each administrator can customize with widgets.
The sidebar menu is the primary mode of navigation. It is divided into two main sections: Administer and Configure. Pages that are used on a regular basis as an administrator monitors the site are in the Administer section. The Configure section has pages that deal with settings and plugins. An administrator uses these pages often when setting up a site, but only occasionally afterwards.
