I know it's there somewhere, but I cannot find it. A couple of years ago I was playing on an MC server where there was a good solution to prevent griefing. The method worked in the way that if a player places a block the other players cannot destroy that block and give a red message saying that they don't have permissions.
I've installed a Bukkit server with plugins "world-edit, world-guard, PermissionsEx". I need to put the block ID in somewhere but I don't know how.
I only need help setting up the block IDs to work with the plugins. I've already chosen the plugins I want to use and don't need recommendations.
