The site award is actually for submitting 10 single achievements (for ten different games). So, if you uncovered and submitted the entire list for Modern Warfare 3, that counts as ONE. If you submit a secret achievement for a game, that counts as ONE. Or even if you submit the color achievement tile for a game (they are greyed out when they are locked) that counts as one. Just remember it has to be for 10 different games. Now, obviously if you have several colored tiles (preferably all) or know multiple secret achievements for a given game submit as many as possible for that game.
yea i was just wondering how do you submit achievement lists ? I mean do you search the web and hope to get them first or does a dev for the game emial them too you? I'm only asking b/c I see a lot of people with that site award and i'm intrested as well into getting it.
