Definitely make sure the GANG newsletter isn’t being put in your spam folder. We have fairly regular (every month or so) events of some sort, and always announce them (and have reminders!) in the newsletters.
We have networking meetings called “GANG Hangs”, often associated with events like GDC, GameSoundCon, or one-of events.
Also, make sure you like our facebook page, as we have online discussions there; online ‘networking’ is almost (but not quite) as important as physical networking these days.
