There are so many ideas racing around in my head, but here are my top two ways to build community.
1. Transparency. Assemble the team and layout the pattern of what the project looks like, the responsibilities, and the people who are assigned. Point out why assignments were made so discussion can take place and expectations stated.
2. Feedback. There are corrections and there are compliments. Sounds true. But in fact, even a correction can be embedded in a compliment. It's not the natural response but it can be done.

Thanks for sharing your article and asking for new ideas. Chris.
