Do children, who are supporter of comradeship, think that working to prevent cyber bullying may be a task for them? This study describes, from a child’s perspective, how a supporter of comradeship can be supportive in the preventive work against cyber bullying. This study will also define the phenomena bulling and cyber bullying, the difference between them and where they can be seen. I will also describe the supporters of comradeship are elected, the information they get from school and how adults at school help them to plan their work. The schoolconsider, of course, the Swedish school law towards (against) bulling and insulting behavior and the school is also visited by inspectors from the Swedish National Agency for Education. The idea to do this study came arise, from a lesson when we discussed, with the pupils, a problem that had happened the day before, after school. It was a problem that was difficult to solve and it was an interesting problem to discuss. I have been interviewing the supporters in group and in pairs. The supporters at the school think that cyber bullying might be a task for them to work with in a preventive way as well as the work to prevent bulling at the schoolyard still is important.
