Removing a menu item from a dropdown bar

Hey everyone I am trying to remove one of the menu items in the navigation bar.  I went to the customize menu in the admin settings but the problem is it only sets what the menu bar will have, not what you want displayed.  Could anyone help me regarding this? I heard theres a file in a part of the elgg installation when I googled this question but that file is now depreciated in 1.8. Thanks!
