Hi Daryl & fellow LDMers,
That SCN most certainly raised my eyebrows when it came in. As you clearly
do, I've got some questions about this too.
I'm going to inquire deeper into what this means, the implications, and
what users (not to mention us at the UPC) should do to adjust if anything.
I'll share what I learn when I hear back.
May we live in interesting times,
-Mike
