SMF is all that in one package, giving you an easy to use forum with many powerful features for you as well as your users. SMF is an open-source free forum software project made by volunteers from across the world.
Simple Machines Forum — SMF in short — is open-source free community forum software delivering professional grade features in a package that allows you to set up your own online community within minutes.
Its powerful custom made template engine puts you in full control of the layout of your message board and with our unique SSI - or Server Side Includes - function you can let your forum and your website interact with each other.
SMF is written in the popular language PHP and uses a MySQL database. It is designed to provide you with all the features you need from a bulletin board while having an absolute minimal impact on the resources of the server. SMF is the next generation of forum software - and best of all it is and will always remain completely free!
