Umm....good guide but one thing to point out since I am a 85 miner from powermining at the Rimmington mine in a full world. If you click the rock at the same time as a lower lvl miner then u that is also mining and they have the faster internet or computer they will most of the time get the ore. I know this because it happened to me a few times where the noob miner(lvl 45) was beating me a lvl 80 miner at the time. :?
