Came across this interesting forum software when looking for a Wordpress integrated solution. http://www.ninjapost.com/ Has anyone ever used this before? How does it differ from Xenforo? What was most appealing was that the forum updates in realtime like a chat room so if others respond to a thread and you are viewing it, it will update automatically without you having to refresh the screen. Does Xenforo do this? Looks like a killer feature for social engagement. What do you think?
