Change the "Create [content type]" title I allow registered users to create content of type X, so they can go to the /node/add/X page and fill in the form. However, I want to give this page a bespoke title, i.e. "Make an X" rather than "Create X". I have tried adding a string override in settings.php, and also tried with the string overrides module. However, neither of these worked.

What is the best way to do this? (I don't want to install another module if I can avoid it, I already have too many and this seems like a trivial issue).
You could do:

function MY_MODULE_NAME_form_alter(&amp;$form, &amp;$form_state, $form_id)
{
    if($form_id == 'myContentType_node_form') {
         drupal_set_title('Your custom title');     
     }
 }
