I'll set the tone for suggestions:
There will be Edicts and Normal Rules. Edicts will be few and to the point, but they Can Not be broken, on pain of Banning or Ejection. Normal Rules are for covering minor infractions, more encouragements then ironclad laws.
Example of an Edict: Do Not Cheat!
Example of a Normal Rule: Please watch the language while in combat with rival clans or in the General Public.
We also need to set up some form of system to vote on ratifying and enforcing these rules. It needs to be efficient and fair.
