All privileges can be administered through the privilege portal, located at the URI /admin/priv/ in installations of LiveJournal. To start administrating privs, you should login as the system account you created in Chapter 12: Finishing Up[6]. By visiting the /admin/priv portal, you can start assigning privs either by username or privilege name.
[6] The script bin/upgrading/make_system.pl creates the system account, and grants it the admin priv with the argument of “all”.
