The Moodle Modules and plugins database is filled with modules great and small. This book will review a range of useful modules and show you how to use them, but first you may want to know how you can find modules yourself.
It is helpful to know where the modules discussed in this book come from, and how they were judged as worthy candidates for review.
You may have an idea in mind, or you may just want to see what's out there. You'll need a web browser and an active Internet connection.
