Overwrite the title for a particular taxonomy page Can anyone help me on how to overwrite the particular taxonomy page title in Drupal 7? 

Let us say I have 4 or more taxonomy page. I need the page title to for 3 pages and not for 1 page. If my url is http://localhost/drupal/companies/* the title should be overwritten as "Hello"; if the url is http://localhost/drupal/technology/* the default page title should  appear.
It is easily done with the Taxonomy Title module.
It adds a "Term page heading" field for terms. Simply edit your term and you'll see.
