BANZAI is organised into sub-circles, each of which has its own coordinator and remit. The sub-circles are broadly autonomous within the scope of their remit, but interact via the General Circle. The diagram below shows the set of circles — the circles in grey currently lack a coordinator and are in hibernation.
