Just follow these simple instructions to get a 48 hour XBOX LIVE GOLD password:
1) Go to http://www.keepingittwisted.com/xbox_register.aspx
2) Fill in all fields (any old gobblydegook will do, the email address field must have the "@" sign and ".com" at the end. Click submit
3) On the next page enter this code exactly "AA4XPN3" (without the " ") and fill in the word verification as it appears in the box.
4) You will recieve a code which you enter into your xbox live account (redeem code) on your xbox!!
You can repeat this as many times as you like by changing the screen name & email fields.
You could even get lucky and win microsoft points (happens approx every 25 codes or so) which you can spend online on arcade games, music etc.
Found this while having a surf around, Let me know if it works.
