I disagree with an agree command. It won't deter griefers that much, and will not be great for first time players who don't know what server comamnds are, and are roaming around wondering why they can't build. That, and it'll require a complete overhaul of the map permissions system to prevent people building until a value has changed, and implimenting a method to store that change, which will introduce many more bugs, and could potentially corrupt storage databases making everyone loose their statistics.
Currently, Half Ops and higher can send the rules to players. This can change with software updates. Players are told about the rules twice when joining the server. Once in the Message of the Day, and once on a message block in the spawn area. They are also told about the Terms and Conditions which cannot be bypassed normally. This is plenty by itself and will stand up in court perfecly fine if anything ever got that far. If a user breaks the rules, or our Terms and Conditions, without reading them, it's their own fault. There is nothing we can do to force users to read it, short of throwing the rules in their face when they join, which combined with the rest of the automated text will fill the chat area instantly, meaning that it'll dissapear when everyone and their pet dogs greet the user on join.
