Introduction To SMF
From Online Manual
Simple Machines Forum — SMF for short — is a free, professional-grade software package that allows you to setup your own online community within minutes. Its powerful, custom-made template engine puts you in full control of the layout of your forum. Our unique Server Side Include (SSI) functions lets your forum and your website interact with each other seamlessly.
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 in 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!
