Yes, it's an editor in the Windows Live suite. You can write/edit your post there and publish it to several different blogging applications such as Wordpress, Blogger, etc. You can also view the post as it will look on your site before publishing. It is an awesome editor and would be perfect for what I want to do on the PortaMx frontpage (when I get one).
I want a blog like frontpage AND a forum. Later I would like to add the individual blog option for members.
