We just got back from our little vacation and I'd like to repost that our "Third World Gamers - What's your Gamertag?" contest is ending soon. Over 18 XBLA promotional codes are up for grabs (which let you play the full version of either TiQaL or Brain Challenge for FREE). The contest will end on April 26, 2008 at 9PM so if you'd like to join in, post a comment in that section right now to join!
Good luck :D
