Simple Machines Forum (SMF)
Elegant. Effective. Powerful. Free. SMF is all of the above. SMF is jam-packed with features, while at the same time having a minimal impact on resources. Some of our features include: COMPREHENSIVE THEMES: Not only can you control the default theme for your community, but you can also allow your users to select from a range of themes themselves BLAZING-FAST DATABASE: Not only do we make use of a MySQL back-end, but we've also gone to great lengths to ensure the database design is fast and efficient SECURE FILE ATTACHMENTS: Our special file-attaching system allows your users to attach files without fear of corrupting your system. AUTOMATIC MOD INSTALLATION: Unique to SMF is our package manager - a system by which you can download and install upgrades and modifications with just a few mouse-clicks SSI HOOKS & API: SMF was specifically designed to be easily integrated with other software projects - use our SSI hooks and API to easily plug SMF into the rest of your site
