Creating this is the first step, don't be put off however if the first few
events are a little quiet. Consistency of schedule (once a month for
instance) is the secret to getting people involved.
I went to a local one just last night (Melbourne, Australia), it has been
running for 3 years now and while the first meeting was just two people, it
is now approximately 15-20 which considering the country is not that bad
really. :D
Building a physical and not just mental community is a big thing and should
be done where possible.
