Do whatever you can to catch factual errors, potential libel and bad writing so editors can tackle the problems and solve them before publication. They learn from the experience without you and them spending hours in the principal's office, or worse. Beware the cookie cutter. Our field badly needs an infusion of fresh design. Maybe you're the adviser to bring it in.
Administrators are our friends.
A friendly, honest and open relationship with your principal is well worth building and nurturing. Your principal has enough worries and pressures without student publications being one of them. The editors should be meeting regularly with administrators to talk over story ideas and get their reactions to and advice for student publications. Administrators need to be a part of the publishing team, not potential adversaries or censors. Know the law.
