If your interested in joining just go to http://www.meetup.com/sdpinball/
and sign up. The site doesn't spam you or sell your info or anything,
it's a legit service and in fact it cost me a few dollars to create
the group.
I know there is a good group of people in the San Diego area who are
into pinball and I think it would be to the benefit of everyone if we
could become a closer knit community.
Thanks!
Matt
