How does `educate_until_posts` interact with the recent changes to `check_education_message`?

The main motivation behind this change was to stop the education message from showing up over and over again. But now that I’ve seen this topic, I think I may have gone a bit too far, since it kind of makes the setting irrelevant if the message only shows once.

I’ll take another look and see if I can find a better middle ground. Will update here once I do.
