One of the greatest assets of GARS lies in it's unique module system that allows you to extend GARS functionality easily and elegantly. GARS comes pre configured with over 10 modules that cover most needs.
GARS groups modules and their configurations into Module Sets. A Module Set is a group of individual modules and their unique settings that may in turn be applied to a type. Modules form much of the core functionality of GARS as they allow you to extend the functionality of a forum in a variety of ways.
