First, U dont have to have an account on entropia tracker, it register all globals/hofs/ath's and the player that got it.
Second, Miningpart is still a little buggy, it dont register all miningglobals atm. It missed 5 of 6 of my globals...
Third, It havent been up and running long enough to give an accurate playerbase yet
Specially thinking about Mining/crafting part of the tracker.
