Yeah looks kind of, cool was thinking, will it work on, phpBB 3 and the INV?
Oh and, have it as a contact I think will do.

Spoiler:

The second part is another code, are what are you exactly wondering?

Xbox360 Developers only allow a limited number of programmers access to their documentation to create such "widgets"/"API". The allow maybe 2 or 3 freelance coders this documentation a year.

You can create something like it in the since where you can place the avatar, points system and call it GamerScore and then have the stars grow when ever they grow. I have a code that will change an image based on a certain profile number.

If you are willing to do a little work this is possible in its own way, it will not be directed to the actual XboxLive site.
