Simple Machines Forum (SMF) is a free software package that allows you to set up your own online community within minutes.
It has a powerful custom made template engine that puts you in full control of the layout of your message board and with our unique Server Side Includes (SSI) 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.
