This is an initial draft.  It's not complete but is far enough along that it's ready for more eyes and comments.
I apologize in advance if this is pedantic bike-shedding.  Are there aspects of being a professional that we care about that aren't encompassed by being considerate and respectful? This word stood out to me in this list simply because many people participate in free and open source software communities as something a bit separate from their professional lives.
