Core protect - If you read my last post in this thread you probably know what log block is. Core protect is just like it but better, Like logblock, you can see who placed or removed a block in a certain area. But with core protect you can also rollback area to a previous state. There are many option when rolling something back. you can wither rollback an area or a player. If you are rolling back an area you can chose the radius which to rollback and the time to rollback to. There is no need for mysql when setting up core protect. all you have to do is add the jar to your plugins folder.
