Your friends aren't gonna know they're admin unless you do commandToClient(findClientByName(name), 'setAdminLevel', 2); 1 is admin, 2 is super.
You may as well just add them to the auto admin list though so they're always admin.
$Pref::Server::AutoAdminList = $Pref::Server::AutoAdminList SPC "their blid";
AutoSuperAdminList for super.
