Well, we tried the new WordPress text editor with blocks, called “Gutenberg”. It was interesting! But a little klutzy, and honestly not that well-suited to this site for most of us, I suspect. So I installed a plug-in that restores the “classic” editor. Now, if you liked the block editor, or would like to continue to experiment with it, scroll down on the post entry page and click the “switch to block editor” link.
Always here to slake your thirst for BMG meta!
