About a week ago, I provided exclusive screen shots of the new Microsoft Live Search Webmaster Tools portal. It appears that as of last night, Microsoft has released the http://webmaster.live.com/ to the public, as a beta.
Ben, Chris and I discussed some of those features on the Search Pulse last night. In short, Microsoft has a long way to go with this tool. Very long way to go.
There is currently not much help documentation, nor support for the tool as far as I can see. You can give feedback about the tool over here, if you are signed into the "Connect site."
