We've been asked what level of explicit content we want to allow on the blog -- PG, PG-13, higher? In discussing biology and especially xenobiology, it can sometimes be necessary to discuss the physiology of mating. Also, some sociology/culture-focused posts might need to address sexual practices.
Is any (worldbuilding-relevant) topic ok so long as it's discussed "clinically"? Are there topics we do not want to see covered at all? What about fiction?
What guidance should we give to authors?
