What device do you have? Chances are if there is a root method its already been found. Check over at XDA Developers. If they don't have a root method for your device they can guide you on how to get started looking for that exploit. XDA is more about rooting, ROMs and the technical side of devices than you are likely to find here. Not that AC doesn't have an excellent tech community, I'd just say that more hardcore devs reside there.
