@Daojoan The people who ‘approved’ it, are the people who voted for public #education ‘leaders’
that shifted focus away from teaching language and critical thinking skills to ‘feel good’ priorities, such as #HighSchool #football stadiums costing in excess of $70 million, all while #PISA standardized test scores in #reading , #math and #science for students in the #UnitedStates have been falling for decades! 🤔

There’s a ‘good’ reason Trump said “I love the poorly educated!”

I got a reply! Which I wasn't expecting, given the time zone difference.

In summary, he wasn't aware, and will try to fix it soon. Given the time zone difference, I wouldn't expect anything until at least tomorrow or later.

Well, I went to the Wayback Machine and found the creator of the site, and his e-mail. I sent a message. With luck we'll see if this was just a website falling down, or if he was winding things up.
