My blog is now running under Community Server 2007
I was amazed to see that my blog at msmvps.com is enabled with Community Server 2007. I can see that most of the settings are same as CS 2.1 except the changes to user interface and theming system. So you can purchase my book - Community Server Quickly and use it without any fear. I already included the new features of CS 2007 on the book.
