Thanks again Blossom, now I'll know what's KDP Select vs. KDP.
I guess I should have figured it out sooner or researched it better.
This has all been new to me since I joined MR in June. There's a lot of info. about all aspects of ebooks, and related, to process and learn. I'm only at a basic level using calibre and the additional "special" plug-ins and have a ton more to learn/figure out (when I carve out the additional time, etc.).
