The Modules page is where you can see your currently installed Modules.
Integrating the modules into your web pages is covered in detail in the Modules and Tags area of the User Guide.
Some Modules include their own Control Panel, enabling you to perform certain actions specific to that Module. For example, in the Mailing List Module Control Panel you can view, edit, and delete subscribed email addresses. You can access the control panel for each module that has one by clicking the name of the module in the Modules page.
