I noticed Greg told us a few rules while we were playing another clan. So here they are as of I know of. There will most likely have more added onto the list.
1. Do not talk in all chat, unless you are leading the group
2. Rule 1 should not be abused for shit talking.
3. Always follow commands word for word with your group leader.
4. Always be a good sport, and call it a good game at the fall of the throne/tree.
5. Only the group leader should ask for a rematch.
