Very true about the bullying.
With technolgy changing so quickly many parents have no idea or concept of what can be done with technolgy.
At my workplace and many others now email, sms and mobile phone equiette have to be taught as many people of all ages use but have no ideas or try to use skills or knowledge from other methods of communication which dont always cross over fully.
I would advise those who are not au fait to do a bit of googling nothing mind boggling all fairly simple but can safe a lot of grief due to a mis understood message or a faux pa made
