I don't think the presence of creators should change how we behave in the fan sphere, and it is still the fansphere. Just because the chef is out in the dining area doesn't change it from being a place where food is being eaten, and commented on. If someone can't handle criticism, they are the ones who needs to leave.
We shouldn't comment with flames to the creators when they are in the forum, but I think that's already covered in the we shouldn't flame other members clause. Like, in response to a post detailing how Joe Q has further ruined Spiderman, I think it's perfectly reasonable for a fan to express that Joe Q sucks...but Joe Q was to show up and comment, it is not acceptable to reply to him in the you suck format. If they are communicating to us using the tools of community members, they should be treated as community members, no flames no sucking up.
