I know this isn't my business i should be delving into ,but I think it would be a big help if we knew what the value of each block was or at least what the basic blocks are worth. Since the /Island Level command doesn't work you administrators could contribute somewhat of an idea of what blocks may be worth so everyone isn't lost about the level of their island. I hope once you get the time you may be able to do something about this!
