It has RTM'd!

The Lync team of writers, both inside and out of the Microsoft, have completed the Lync 2010 Resource Kit. The ResKit (not to be confused with the Resource Kit Tools) breaks the content into multiple chapters which can be downloaded individually or as a single ZIP file; the download page is located here. I was lucky enough to help in the process, editing and reviewing many of the chapters (bolded below) so check out the FREE book downloading it today.
