If anyone needs any help understanding this, go ahead and ask - at one time my database was "burning memory" since I had a plan to classify everything (loots included) by zoneid the loot numbers were too high, and caused everything to eat up memory. After a lot of thinking, not to mention I have a good friend that "tutors" me through situations like these (he's not a "MONKEY" programmer like me
), I learned this method, and it's been very helpful for many situations.
