In order to clarify the current set of rules and cover more situations, I've rewritten the set of rules. Please give them a quick read over to make sure you're familiar with them.

Most notable is the addition of rule #7, which I believe is needed after a few incidents. It goes as such:
No lagging devices: no devices that create a noticeable amount of lag or stress on the server are allowed. This includes but is not limited to heavy redstone mechanisms and large amounts of animals.

Thank you for being considerate toward your fellow players!
