Here I'm going to show you some absolute paths in PHP and Drupal that you might need.

This is a module, well actually it's a content filter, that let you as an administrator choose how many links that should be allowed in the content. If there are more links (than you allow) available in the content  they will be filtered out and hence not visible when viewing the node.

This is the official home page of the Drupal module RequireMenu.
I created RequireMenu simply because some content types always should have a menu item, and since Drupal does not offer this I made a module to do it. Look at the screenshots to see the feature in action.
