This book writing stuff was so much fun, I'm gonna do it again... this time on Sametime Administration!
Since I didn't learn my lesson the first time, I'm going to try it again... Marie Scott and I are joining forces this time with Gabriella Davis to write a new book on Sametime Administration for 8.5/8.5.1/8.5.x (whatever version happens to be current when the book gets to the end). This book will take you from either a fresh install or an environment that needs to be upgraded, and walk you through all the new pieces you'll need to install, configure, and monitor. It's definitely much more complex than before, so learning from Gab and Marie will get you moving in the right direction quickly.
We have the outline in place, and hope to have it ready to go in the 3rd quarter of 2011. I should be thoroughly bald by then, having torn out what few hairs I have remaining... :)
I'm again honored to be working with *very* intelligent and experienced colleagues, and I'm looking forward to what we end up with as a result of this collaboration.
