How do I remove the tab provided by a third-party module? I'm using the Guestbook module version 6x-2.0. How do I remove the "My Guestbook" tab on user profile pages?
I solved this with the Tab Tamer module.


  Tab Tamer is an administration utility that provides easy re-ordering, hiding, and deactivation of tabs and subtabs.
  
  Tab Tamer makes use of Drupal's drag ordering, but degrades gracefully when javascript is disabled.
