See this thread on NZRaG:
Oh man, why can’t my larps be this immersive? Being beaten by Shadowrun SUCKS. 
Don’t know about the rest of the LRP clubs - but Quest has a strict nutter-screening policy. We have enough grief as it is with certain fundamentalists accusing us of being demon-worshipers.
nutter-screening is always useful
That’s why larp should be made known to public as much as possible by sane people, like those in NZLARPs. Otherwise the only way for the rest of the Earth population to get some info about larpers are articles like the one about this elf guy, after which it would not be surprising that they think we are all freaks.
