I'm on a mission to get some attention from DJI's support team.  It seems I'm not alone, but there are so many forums and options out there it's easy to overlook some.  I'm hoping there's strength in numbers, so for the benefit of others, here's a list of what I've found so far.

Three groups on Reddit...
DJI Owners     https://www.reddit.com/r/dji/
DJI Phantom    https://www.reddit.com/r/djiphantom/
DJI Inspire    https://www.reddit.com/r/DJIInspire

DJI's own Forum ... http://forum.dji.com/forum-68-1.html
Phantom Pilots ... http://www.phantompilots.com/
On Twitter, the offical feed for DJI is @djiGlobal, and there's always the #drones hash-tag

Do they have groups on Facebook?
Are there other forums / groups I've missed?

Here are a few more...
