I’ve been searching for this kind of Software for a long time and finally, something has been build. I’m taking about a simple forum that you can customize for different niches. The Software is called esoTalk and its free, open-source that is written in PHP and Mysql (meaning it can run and 99% of the servers out there). The forum was build to be extremely simple, fast, modern and containing all essential features that a forum might need.
esoTalk has been built from the ground up taking advantage of all modern technologies providing the perfect balance between simplicity, speed, scalability and power. The forum software also comes with a awesome plugin system allowing developers to extend it so they achieve their specific goal.
