A couple weeks ago Microsoft Promised Webmasters a Live Search Portal.
Part of that included the ability to be part of the beta, to test out new features. Some Webmasters signed up and have already been invited into the beta.
Starting this Friday, on August 31st, Microsoft began accepting webmasters into the beta.
Microsoft requests the URLs you want to add to the webmaster portal and as of now, you wait. There are currently no reports of the URL to the beta login area. There are also no reports of what the interface looks like and what features it has.
But, people are now being accepted into the beta.
