Administration Menu Module
The Administration Menu Module adds a nice little menu to the top of your Drupal site that gives you access to all the Administration links. Why would you want this? It is extremely easy to access your administration links and it doesn't matter what them you are using, all of your administration links are located a the top. I would highly recommend downloading this module.
You can find the module here http://drupal.org/project/admin_menu
