Hide "All" tab from /relationships page..

Do you mean that something like

function hook_menu_alter(&$items) {
  // Example - disable the page at node/add
  $items['relationships/list']['access callback'] = FALSE;
}

should be placed inside my template.php ?

Where is the place that i can place the hook menu alter function?
I searched all the files of the user relationships module but I did not find how to remove the first tab (All relationships) from view.

Hi again,

Can someone help me to solve my problem with the all tab on My Relationships page?
I want also to hide the elaboration message from the table list of my friends. I believe tha the elaboration message is usefull only once, before someome become friend to another. After request acceptance it is not very nice to display the initial elaboration message on My Relationships page.
Regards
Alex

Ok i found the answer .. It has to do with the template.php
http://drupal.org/node/68792

function yourtemplatename_preprocess_page(&$vars) {
  // Remove undesired local task tabs.
  // This first example removes the Users tab from the Search page.
  snd_removetab('******', $vars);    //The '********' is the caption  of the tab that you don't want to display for example 'All relationships' 
}

function yourtemplatename_removetab($label, &$vars) {
  $tabs = explode("\n", $vars['tabs']);
  $vars['tabs'] = '';
  foreach ($tabs as $tab) {
    if (strpos($tab, '>' . $label . '<') === FALSE) {
      $vars['tabs'] .= $tab . "\n";
    }
  }
}

drupal_rebuild_theme_registry();  // Optional ... I am not  sure if this line helps.... :) 

Be sure that you have replaced the yourtemplatename prefix on the two functions with your template name and that you have cleared all caches to see the changes.
The drupal_rebuild_theme_registry() I am not sure it is working and how affects the theme registry.
