Today in class we agreed that:
Everyone will be an operator (to spawn items)
Do not use TNT (this is a building, not destroying game)
Do not use bedrock (because it cannot be removed)
Game will be in Peaceful mode (no monsters)
No killing other players
No attacking other players (we may build a combat area and/or spleef arena)
No portals (because they have scary sounds)
People will be able to fly (but no other mods)
