The forums seem simple, pleasant and fairly snappy to navigate. I've recently been looking at 'head-less' CMSs. Does anyone know of forum software that separates the head from the backend via a well described API? I'd like to be able to embed a forum into a front end application that I already have, so having a 'head-less' forum would be pretty useful.
