It's me again, the Marketing guy from the Knowledge Network for Microsoft Office SharePoint Server 2007 team.  We have released our first candidate (RC0) for our final build of KN.  To access the new build login to the Microsoft Connect site (https://connect.microsoft.com/knbeta) and follow the Downloads link on the left hand side to access the software package and documentation. This release features the following enhancements:

• Back-off functionality to improve the user experience when they are performing activities on their machines.
• Various performance enhancements on both the client and server.
• Improved keyword quality and generation.
• An inner circle web parts that highlights people closest to you and who are most likely to assist with your query. 

We hope you are as excited and enthusiastic about KN as we are.  Enjoy!
