Ning (the social networking platform we're built on) has added a useful Groups function, so we've used that to start user groups.
If you have an ArduCopter or are using APM for a fixed wing aircraft, please join the relevant user group, which you can find in the column on the right of this page. Anyone can join these groups. (There is also a group for the site moderators, which you must apply or be invited to join).
User groups allow you to have more focused discussion on the specifics of one product or use. You can send messages to all the other group members, without the risk of spamming the entire site. And there is a Comment Wall for ad-hoc conversations that you may not want to bother the entire DIY Drones community with.
If there are other products you'd like us to create a user group for?

I imagine that community members will propose user groups for the UAVDevBoard, which only has a maillist right now, and perhaps for products not developed by this community, such as the Parrot AR.Drone.
