The information given by /rules has been given a major overhaul by Tatankore, it now looks prettier and displays a lot more information as follows:
/rules - lists the rules, they haven't changed but look a lot nicer!
/rules 2 - lists globally banned items.
/rules 3 - lists items restricted by rank
/rules 4 - lists other restrictions (disabled clicks etc)
/rules 5 - lists available ranks, with colours
/rules 6 - lists protection stone types and limits by rank
This basically means everyone can check a lot of the information currently at spawn without needing to go there.
Enjoy!
