Flarum

Have you ever used Flarum before? It's a free forum script written in php that takes a more modern approach. I've used it before and it's okay. I used to really dislike this software because I wasn't a fan of how the index page is compared to traditional threaded forums. I still prefer threaded to modern forum platforms though. There's also a free forum host called Free flarum if you want to try out the software without needing to pay for hosting and installing the software yourself.
