I just happened to notice that mine seem to start from when I switched to direct log-in, the first being the email confirmation, and there is nothing for the months before that I logged in through FB... just a thought.Those emails are actually sent by another department which does email's for all of InnoGames games. I do not know what the criteria they use is for them
Thanks for the heads up! I got them!If you check the email address that is linked to your account, they have sent out an email giving away 100 free keys. But you can only claim it once, so choose carefully which city you want them to go to!
