Ah, the beauty of the internet and how it is much easier to make additional content available to customers... :)

 The Server User Assistance and TechNet team recently published a very detailed set of web pages on server manager at http://technet2.microsoft.com/windowsserver/longhorn/en/library/5900586c-3c32-4d28-9c52-492d1ecbeeed1033.mspx 

 Computer World also has an article on Longhorn Server Beta 3 and Server Manager is one of the highlighted improvements in the new OS. The article is at http://www.computerworld.com/action/article.do?command=viewArticleBasic&taxonomyId=89&articleId=9018562&intsrc=hm_topic

 Last but not least, we had a webcast last week on Server Manager that is now available on demand at http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?culture=en-US&EventID=1032336481&CountryCode=US
