Changing the Node Creation Title in Drupal..

This should do the trick in your custom module, just be specific to the content type.

<?php
function your_module_form_alter(&$form, $form_state, $form_id)  {
  if (
$form_id == 'contenttype_node_form') {
   
drupal_set_title(t("Title you prefer"));
  }
}
?>
