Our universities especially here in Sydney have so many different groups available to students and members of the public I am surprised no one has tried to set up before. As I am 26 and now graduated, I have the time and knowledge to build this up into a successful sorority. I am in development and research stage at the moment. so any one that has gone though this process I would love to hear from you PM anytime.
(MEVARA) Its funny you should mention NPC as I thought they might be interested but I think local may be the way to start, from there we can develop our own Nationals with our own rules and governing bodies.
As far as AGZG comment is concerned luckily, Australian Woman can have a laugh
