As from about midnight last night I installed a addon that keeps track of all actions placed on the server. This is to rollback any annoying actions by griefers and letting us know who to ban. There are two ways to track the griefers. First is to simply get a golden axe (286) and right click the block and it will give a full update on what went on in that block. The next is too place a bedrock block in the place you wish to examine and it will alsso give you the info on that area. Other commands including rollback can be found by typing /lb ?
