The true power of Joomla lies in the application framework that makes it possible for thousands of developers around the world to create powerful add-ons that are called extensions. An extension is used to add capabilities that do not exist in the base core code. Trapezoid selects, certifies and integrates and provides code maintenance and service support for all Joomla extensions. Here are just some examples of the hundreds of available extensions:

• Dynamic form builders

• E-commerce and shopping cart engines
• Forums and chat software
• Calendars
