This was originally posted on the blog by Jehosophat on December 5, 2011. We still use this plugin on our servers!
Just a quick note to all of our Minecraft server users that we have disabled Blocklock, which was previously used for locking chests and furnaces. We are now solely using Lockette for this purpose. We did allow about a month of overlap to give everyone time to convert to Lockette.
If you still are unfamiliar with how Lockette works, please check out the tutorial here or speak to one of our ever helpful mods; they are more than willing to help!
