Digital Citizenship is a tricky thing to deal with. I think many kids are understandable and already good about this at school, but of course this will still have to be dealt with. I think that usage of equipment and common sense and manners and things that I will be stressing. It is amazing what can be found on the web to help with this.
We always email with parents through our own website and through a system called Charms. This will still be done, and I think through constant communication things can be done.
