I have recently got an Xbox 360, and have decided to add my gamertag to my blog. This can be seen in the right side of the page and displays my gamer statistics and games played.
To display your own gamertag in your blog or web page just simply include the following code:
<iframe src="http://gamercard.xbox.com/REPLACE-THIS-WITH-YOUR-GAMERTAG.card" scrolling="no" frameBorder="0" height="140" width="204">Put your gamertag here too.</iframe>
Where your gamertag is put in at the obvious places.
