How do I add the flags to a region? I tried a few thigns but thye don't seem to work. Can you show me an example flag? I tried the following. Made a Region named "Keep" /flag add keep break /flag add keep Creeper-explosions Neither of these seemed to make the blocks unbreakable in the Keep region nor are the Creeper explosions not causing damage to blocks. Thanks, John PS: When Break is set can ops still break blocks or does it stop ANYONE from breaking the blocks?
