Avoid anything that even remotely looks like a power struggle today. There are some big egos in on the fight, and some of they like to play dirty. If you get involved in any of the mudslinging: even if you jump in just to quiet it down: you will get covered in dirt yourself. Your ability to play peacemaker is strong, but you don't have to employ it every time you see two or more people clashing. Consider what is best for you: let them argue things out and find their own solution.
