Fantastic Add-on. I really recommend this to anyone trying to run a gaming centric forum. I've actually removed my normal forums from navigation and I use this plugin exclusively for my new forums because it looks more professional than a generic forums.
This has always been one of my favorite add ons change your forum into a real interactive site for your members. I enjoy the fact that you able to move away from your forums theme but also not make members feel that other types of forum topic areas are encroaching on your core forum gene.
