how to remove some staff links..

[php_bug]

Hello all,

since from last 4-5 days I am changing so many things in the support suite, now I want to change some thing but I am not getting it.

I want to remove the link
'Home'->'Private Messages' and 'Tickets'->'Preferences' in my staff CP login.

I think something in the \locale\en-us\en-us.php ,

1 => array (0 => array ('Dashboard', "index.php?_m=core&_a=dashboard", false, true),
1 => array ('Preferences', '#', true, true, array("dpreferences", "MENU_PREFERENCES")),
2 => array ('Private Messages%PRV%', 'index.php?_m=core&_a=privatemessages', true, false),),

I commented this array index [2] but still I am getting this link, I do not know how to remove it .... Plz guide me... this is not the one link , I have some 4-5 so I wanna know how to do it...

thnx in adv for help....
