You've already read our thoughts on the new Xbox Live dashboard update, and now it's time for those who put in their name for the preview program to join the fun. Microsoft today began sending invites that'll get you set up for the download, so that you can enjoy Avatar marketplace and a slew of new Netflix options (and irksome restrictions for Starz Play titles). Registration is still open if you still want a shot at nabbing it before August 11th. Didn't get an email? A second wave of invites is going out tomorrow, but also be sure to check the Connect site you registered at anyway, as Microsoft notes those who opted out of receiving emails will have no other way of confirming.
