I think people who help out allot should be rewarded with their own rank some thing like a BAT (

I remmember saying that the jail command glitched in remove triggers, and I just thought of a fix for the problem. You should have it check if the jail can be spawned by making the cage and checking if it's still there after point two seconds and if it is it makes the cage non removable, but if it's not it should give the caller an error, and freeze the player instead.
Finally the jail should have an optional teleport feature where you could have the player be moved to where you are looking and then jailed.
