Specialized Modules and Features
There are quite a few other modules listed on the module configuration page which have not so far been mentioned. In this section, you'll find descriptions of some of them. Some are currently running; others are turned off. You can also load other contributed modules by downloading them from drupal.org and installing them yourself. Make sure that they are for Drupal 4.5 or they may not work.
Always remember that whenever you enable a module, you should check any permissions the module might have associated with it in order for users to have access to the module. When working with permission settings, it is often useful to create a test user and grant them the role for the permissions you are enabling. Then login as that user and verify that you have indeed granted the permissions.
Also check the administration menu and adjust any configuration settings. Some modules may have their own listing in the top tier of the menu; others may have a listing elsewhere, such as within the settings area of the menu.
