User blog comment:Wave J123/No more achievements?/@comment-5108008-20120324040358

SulthanA, during your absence, the Wiki Council (which includes admins and several normal users including me) have decided to remove the acheivement, as some person might cheat to get a really cool badge and be No. 1 on the leaderboard. So yea, acheivements and badges are gone now. :(
