Regarding the /remove items -1 command... it works a treat... However, can anybody tell me what mod/component it is in Tekkit that allows the use of this command? Anybody know its permission? I would love to give this permission out to several people, but don't wish to OP everyone to grant them the ability... Cheers Edit: Think I have just found the answer to my own question... WorldEdit I am guessing the permission would be "worldedit.remove"
