Ok, so for sheer simplicity, I paid for a WordPress account and copied the blog contents over to it, in part because I genuinely am not sure how the current nevernotlearning.com url resolves at all, since it’s pointing to a defunct address that is somehow ending up at my Lightsail install maybe? I am genuinely not sure, because all indications are that it should not work.
Anyway, I directed the DNS to point to this address, and hopefully that will work with a little time. If not, I may let WordPress manage the DNS, but I kind of don’t want to because they seem bad at it (they charge extra for very basic stuff like privacy protection, and if I decide I want to leave WordPress, I don’t want to have to fight them for the domain name). So, the next part is a bit of waiting, which I stink at, but so it goes.
Never Not Learning 
Semi-success. I found where WordPress keeps their blognames, and I think that was what was keeping the old link functional. Have updated, but they say it may take as long as 72 hours to propagate, so time for more waiting.
Annoying, but if this works, it’s the last administrative task I need to do before this ‘just works’ (excepting one or two remaining layout questions that are non-pressing)
Oh, ugh, it’s a forward. That’s disappointing.
Oh, whew. Just turns out there was one more setting left to switch. Looks like we’re open for business.
FWIW I saw this post in my feed reader, and it linked through here at https://nevernotlearning.com/2018/11/18/quick-test/.
Awesome, that was the the thing I realized I needed to test this morning!
