Over on the Mail Support blog they've confirmed that users on Live Mail will be able to access the new Windows Live Account pages by the end of this month. Users won't have to do anything to take advantage of the new site (account.live.com), and will be moved across in batches. We posted a preview of Windows Live Account back at the end of March. Although parts of the screenshots are likely to change, here's what we said back then:

Account Services is an existing Passport site but as Kip mentioned in his post on Windows Live Answers, we're expecting to see it develop substantially as it switches to Windows Live. Micropayments (Live Wallet) and rewards integration (Live Points) are two of the main contenders, managing your multiple personalities with Live ID is another. As with the existing MSN Account Services site, child protection plays an important part. Family Safety Settings makes an appearance, and as has been noted before, will provide a way for parents to monitor their children's Windows Live experience by controlling who they can contact via Messenger, Mail and Spaces.
