Richard Hector (richard@walnut.gen.nz), I am considering the case of (production) systems on TV stations for general audiences, that is TV stations that is watched by all audiences, not just teens. As long as someone is aged 13 or older, he/she is teenager. The remaja user group is for anyone that his/her age is 13 or older. My concern here is whether giving teens full administrator privileges on those production systems can be dangerous/vulnerable or not, in fact that psychologically they are very unstable.I think we (or at least I) must be missing some context here. For starters, this must be some specific group of teenagers. And I'm sure they're not given permission to take over running the whole TV station. Is this some specific educational environment? Or is it a TV station specifically intended to be run by and for teenagers? Something else?
