newbee: How to hide a menu item so only admin sees it?

Under Administer->Blocks, create a new block with this php code:

<?php
global $user;

$output = ' ';
if (is_array($user->roles) && in_array('admin', $user->roles)) {
  $output .= '<ul><li><a href="?q=[Drupal Path]">MyMenuItem</a></li></ul>';
}
return $output;
?>

In the [Drupal Path], write in the path to your node. For example, to link to the user search page, you would put in search/user (without the brackets) for the path. In the Input Format area, select the PHP code radio button.

And you need to disable the menu item in administer->menus because you don't want it to show up on your navigation menu. It's now inside the block.
