We started as an Adobe Flex user group. Flex is an opensource development framework from Adobe that allows the creation of so called Rich Internet Applications that run in the Flash Player or within AIR.
Now we're the Flash Platform User Group and it's a loose community of people working or being interested in the Flash platform, particularly in the Flex framework but also with other Flash-related technologies. We meet monthly in Wellington, usually on the second Wednesday of each month but YMMV on that. Most of the meetings will feature one or two presentations discussing various topics about Flex or topics that are sort of associated with Flash (Flash Player, hooking Flex into various backends on the server, other RIA technologies, AIR etc.)
We have a google group for further announcements and technical discussions:
