1. You're assuming there are far more wand locations than there really is. Go ask on officials and see if they will answer the question again, but if you search you can find it. Pretty sure the number is under 100 officially, but if it is over it isn't very much over. All those other spots you've heard of are either old spots or were never spots to begin with.
2. You aren't allowed to share wand locations OOC. Yes, some people will do so if you contact them by AIM or by PM. However, those people are poopy head cheaters. I for one think you will get more out of the game if you get yourself a high level mage, get detect artifact, and go exploring. Even if exploring isn't your gig, you will find other shit that will help you in your PK game.
