Both xbox.com and the forums will be down for a short period of time while the update takes place.
A highlight of the changes are as follows:
- Browser based Avatar editor: Edit your avatar and preview avatar items before purchase
- Combined views for messages, friend and game requests
- Improved notification of your account subscription
- Leverage Family Reports to understand what your family is doing and how they are using LIVE
- Play web games with your Xbox LIVE friends on the web or on Windows Phone 7
- Marketplace: More powerful search and more intuitive ways to browse and filter
Initial opinion is that it looks a lot cleaner and fresher than the old design and a lot easier on the eye. The ability to edit your avatar online looks good.
