I did try to read back and did not see this previously posted. Now is this a bug or an intentional feature?
When you download gamertag from xbox.com all fine. your gamerscore is xxx, then if you play 360 games and improve your score they don't seem to update on xbox automatically? I keep having to re-enter my gamertag, is this a bug?

Its not a bug per say.

You only obtain the info once, untill you manually update it. Well when 1.0 goes public it will update you gamescore when you boot the skin, so everytime the skin loads it will update the gamercard stuff.

nice
