Wow, fantastic presentation although I would recommend a MS presenter mouse (PPT buttons on the bottom)  so you won't have to run back and forth like a mongoose on methamphetamines Smiley but I must say having done maaaannnnyyyy presentations myself this one was a 10. Thank you so much not only for RX but also for your energy and clarity of presentation. I am doing extensive Lync/UCMA work and the entire API is async method pairs for this RX is a godsend.
