New HCL whitepaper on Sametime chat server on Windows

HCL has just published a whitepaper that explains how to install Sametime 12.0.3 on Windows step-by-step, run it on the same computer as an existing Domino server, and
customize the user interface.
You can find it here https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0129431

This post is a shameless plug because the authors of the whitepaper are the Sametime expert, HCL Ambassador, and friend Aleŝ Lichtenberg and me.
