Bukkit

Permissions Nodes are:
chestrandomizer.worldname.<command>

where command is one of the ChestRandomizer Commands. If a player tries to use a command for which they do not have permission, they will be killed.

available commands, with basic synopsis:
repopchests
repopulates chests. This is also issued automatically when games start.
preparegame
prepares a new game.
joingame
is issued by players after an admin issues /preparegame to prepare the game (or anybody with perms). It will join that game event. The player will be teleported to the appropriate world at the location the player who issued /preparegame was when they issued it.
spectategame
same as above, but the players will be spectators. This is supposed to allow spectators to be invisible and observe the match without interfering with or distracting players, but I have had reports of some minor issues in this regard that I have not yet been able to investigate.
mobmode
toggles whether a game that is prepared will be a mob arena game or a standard PvP arena game.
mobtimeout
is used for PvP matches. provided with an argument, it specifies the number of seconds before the mob spawning algorithm will be re-enabled. The mob spawns will be the same as those you would find in the Mob Arena Mode, but currently the caps and spawnrate are not changed.
mobsweeper
so-named since it is designed to "sweep out" players that are camping. Force-enables the Mob spawning algorithm described above.
repoptimeout
sets the timeout value for opened chests.
newarena
generates a new arena and teleports the invoking player to it when it initially generates.
borders
shows you the currently set borders. /newarena will initialize the border values to the size of the created arena.
arenaborder1 and arenaborder2
set the corners of the border for a rectangular region.
setlives
sets the number of lives each player has for both PvP as well as MobArena Matches. 0 indicates infinite lives which is a flag for a continuous game.
