Ollie - I read up regarding this guy's condition of megalomania and here are the defining characteristics :-
Megalomania is a psychopathological disorder characterized by delusional fantasies of power, relevance, or omnipotence, "Megalomania is characterized by an inflated sense of self-esteem and overestimation by persons of their powers and beliefs.
I really couldn't have put it better - it defines him to a 'T'.
The prognosis isn't encouraging either I'm afraid because it basically says he will disappear up his own ass in a puff of reality .... I am gonna be his puff of reality.
I certainly do not wish to elevate myself here or make myself look good in any way, that is not what I'm doing - if I was to use a metaphor for my role in this, it would be as a broom in clearing the sh!t out of paintball, nothing more, nothing less ... he has attacked a lot of people in our industry and they elected not to do anything about it preferring to let the prihk do what he's doing ... it was inevitable he would attack/threaten one person too many ... this explains this whole thing.
