That's the only one I know of. Until Xenforo builds a proper CMS our options are limited. There is a way to create raw pages but I haven't figured that out yet and it seems a bit of a nuisance to use. There was also some talk of using Wordpress but then you have to bridge it in with Xenforo and that's were the problems start. More pieces means more breakage. Having everything inside Xenforo would be better.
