In the interest of keeping the group in harmony, encourage compromise. There is a lot of subliminal stuff going on, and people don’t all share the same goals. To make sure that no one person uses the group power to get what’s best for only them, you’ll have to keep a sharp eye on the prize. Reinforce what goals everyone should be working for. Don’t let one strong personality hijack everything for their own gain. You have the skills to keep things civil.
