Details

Array of usernames who will be sent a notification email for every change which occurs on a wiki.

Example:

$wgUsersNotifiedOnAllChanges = array( 'WikiSysop', 'User123' );

Note: before r32683 in 1.13alpha, this was misspelled $wgUsersNotifedOnAllChanges!
So for version pre-1.13alpha it should be as below.

$wgUsersNotifedOnAllChanges = array( 'WikiSysop', 'User123' );
