+1)	Do not attempt to crash, lag, damage, disable, exploit or disturb the server or game.
+2)	No greifing (affecting other creations and buildings in a deliberate and destructive manner)
+3)	Don't be harrassful. This includes (but is not limited to) asking for stuff constantly, being rude or inconsiderate and spamming.
+4)	Everywhere in the world is free to walk around but if the area is clearly private stay out!
+5)	Do not take anything which is not yours unless otherwise stated.
+6)	Punching other players (PVP) is only possible when all players taking part agree.
+7)  Multiple accounts are dissalowed and you are responsible for looking after your account and login details.
+8)	We want to make this world look as nice as possible, so please avoid building 1x1 towers or tunnels and placing random blocks everywhere. A few cool buildings would be nice too :)
