If you are a person starting out with Drones, there are many things to know.  Some will be simply how to fly a drone safely and legally, while others may need help with getting their Part 107 designation (for the non-USA people, this is the USA Commercial License), as well as photography tips.  Here are some good Facebook groups you can go to.  Some are lighthearted, but still offer good advice, while others are specific towards photography, the Part 107, airspace, etc.  Click on highlighted text for the group.

Mad for Multi-Rotors – A good social group.

Drone Pilot Profits – A group dedicated toward the business side.

DJI Drone Photography – Assistance with photography, but obviously focused on DJI drones.

UAV Airspace Classification Discussion – A specific site where you can ask questions about airspace rules.  For the Part 107, this is critical.

Drone Days – Another good social group, where beginners and experienced pilots can discuss and post their questions, photos, videos.

UAV Drone Aerial HD Photo & Video Gallery – Another group based more on photo and video, but not brand specific.

Feel free to reply to this post with groups or webpages you think are helpful, and I will amend this post.  Note – I will screen all replies first to ensure the websites are appropriate.  Be patient as I have a day job, but I will post all good sites.
