Somehow I got another alpha key if anyone wants one. Here's the email info they sent:
July 20-22nd - We will be testing the four human races in City of Steam and making sure everything is nice and smooth. Play as a human (Aven, Heartlander, Stoigmari).
July 27-29th - Elves enter the mix: riven and draug!
August 3rd - This alpha test weekend you'll be able to play as any of the greenskins - goblin, hobbe and orc. Bringing the total to 9 playable races!
Also, here's the activation page for the key: http://www.cityofsteam.com/cityosweb/default.php/gamekey/index
