They are an anti-bullying charity. They do some very good work with schools and with individuals. When we pulled DS1 out of school because of bullying, I enrolled him on their Zap course - aimed at victims of bullying. It was a great course and they catered for the parents too, so that we could talk through our experiences and how we had been affected by our child's ordeal.
They have done a lot of research and, as with most charities, are dependent upon donations and whatever they can raise through their courses - which is not much as they don't charge much.
