Go
here to change your xbox life gamertag for free to one of the new system gamertags.
I'm not sure if this will work for everyone because this is a US link,
Since the new gamertag feature hasn't been implemented into the xbox yet, you will see some numbers added after your gamertag if you take one that has already been taken. Let's say you take "Memelord" it will look like "Memelord1045" and when the new features get added sometime later, it will look like "Memelord #1045"
