Here is a birds-eye view of what's new in the area of ADFS Documentation for 2007: 

• More blogging - including new blog posts in February from our new ADFS SDK programming writer (Jim Causey)
• An additional writer will be coming on board to help with IT Professional-based ADFS documentation
• Updates for the R2 version of the ADFS Step-by-Step Guide
• Updates for the Longhorn version of the ADFS Step-by-Step Guide
• Updates for the ADFS Deployment and Design Guides
• Updates to the Troubleshooting section of the ADFS Operations Guide 
• New documentation for CTP customers that will cover the next generation of ADFS (also referred to as ADFS 2.0)

I'll post more info in the next few weeks about the things we are planning for the ADFS Documentation Blog in 2007.
