Extensions are downloadable packages which can be installed very easily on a phpBB board to add new features and functionality.
Extensions are the natural successor to modifications (sometimes known as MODs), the development and support of which have defined the community's involvement in the phpBB project for over a decade. Unlike modifications, the extensions system for edit-less changes in phpBB 3.1 makes customising phpBB easier than ever.
