I'm thinking they should add a 'legal' page, where they can notify potential UAV pilots of laws they might break accidentally when flying these things. I'm sure there are a few regional restrictions in addition to any federal ones.
In the spirit of other hobbyists the DIYDrones community often laces their posts with warnings about heeding local laws. Larger projects are often based from airports so talk is had about regulations involved as well.
Aside from the individuals on the site asking others to research and listen to local laws/regulations articles on laws around RC craft and drones in various nations are also posted frequently.
It's been lovely seeing the community grow. Welcome all.
