FeatherBB is an open source forum application released under the GNU General Public Licence. It is free to download and use and will remain so. FeatherBB is a fork of FluxBB 1.5 based on Slim Framework and designed to be simple and very lightweight, with modern features: MVC architecture, PDO, OOP and a plugin system. Maybe more? You are more than welcome to join the development :-)
