SOCIAL RULES

1. No Griefing 1a. Griefing is more than just destroying blocks. It can be being extraordinarily annoying, stealing shit, whining, etc.
2. Don't be a douche
3. Listen to the mods / admins
4. Don't ask for promotions to mod / admin groups.
5. Feel free to ask the mods / admins for help with anything, but don't expect them to give you everything you want.
6. There is a 3-strikes system for administrative action. First offense is a warning, Second offense is a temporary ban (up to a week), Third offense is a permanent ban.

GAMEPLAY RULES

1. No more than 2 Quarries per person running at any given time, 4 per party. 1a. Quarries must be admin approved and placed by an admin.
2. If you are going to make a Nuclear Reactor, it must be surrounded by a 3-thick wall of Reinforced Stone, to minimize damage in the case of a reactor meltdown. You also need a permit from the mods / admins. 2a. You are responsible for any damages caused by your reactors, so follow the above rules to minimize damage!
3. Limit 5 auto-block breakers per person.
4. If you're using Buildcraft pipes, YOU MUST HAVE OVERFLOW CONTROL. Overflow control can be as simple as Lava below any areas that an item can flow out of the pipes if the recieving block is full. IF YOU DON'T HAVE OVERFLOW CONTROL, YOU MAY CRASH THE SERVER / CAUSE LOTS OF LAG AND YOU WILL GET A STRIKE.
5. Not so much a rule, but try not to have enormous redstone contraptions that will cause lots of lag in an area.
6. If you're going to use a Filler, you must A) Get a permit from the mods / admins, and B) Collect all the drops that are on the ground!
7. If you wish to claim property as your own, make an obvious border around it (scaffolds / fences work well) and put a few signs around with your name on it. 7a. You can also claim a building as your own with a sign on it with your name. 7b. If you REALLY don't want people in your base / property, put "NO TRESPASSING" on your signs, and then feel free to arm your base with any defenses you want. Dispenser / lava traps, tesla coil, the works. ;)
