I have installed BBpress as a forum for ByteClub.
Have a look at forum.byteclub.net
BBpress shares the same user table with wordpress, so your WP login will work on the forum too. There is suposed to be an option to share cookies between the two apps so it acts as a single sign on system (Currently you have to log in to both serperatly. Meh), but I haven’t got that working yet.
