I need to set up a simple forum/BB for the game I'm developing. there's really no need for anything fancy (like pic related), I just want something in which you can have boards, threads, et cetera
what should I use?
Just go download FoolFuuka and get moving.
It is sad seeing a game get developed in Unity or something else that supports Linux and the developer only releases in Windows. It is like they don't want to make money.
