Let's change the perspective on Maston by referring to the administrators as "Amateur" administrators alongside the "Hobbyist" designation.

I am an *amateur* radio operator licensed by the FCC. The *amateur* is important since it says I am a professional in my activity but don't get paid. It is also a hobby.

How can I say we are professional?

One reason is we are the only group in the US (and maybe elsewhere) that can build a radio transmitter without having to submit it to the FCC for approval.
