So the lesson is: stop being ass-hats. Be nice to each other. Stop the petty OOC rivalries, stop busting people's balls over stupid things to the point where they feel they need to lash out in retaliation. Don't play to win - that usually leads to bending shit in your favor and at the expense of others, which in turn leads to fighting. Have common courtesy. Don't lie in OOC. Simply put: get-the-fuck-along.

Sincerely, your friendly neighborhood, neutral spectator.
