Just in case anyone’s looking, here’s how you disable comments in new weekly artifact posts, so reviews end up the right location:
Edit Post > (read it to make sure it’s yours first)
You have to be able to “see” the settings for “discussion” first before you can change them, so turn this on in your “Screen Options” tab at the top of the screen:
Now that you’ve turned on the options for “discussion,” scroll down and look below your post for the “discussion” box
un-check the “allow comments” field > click the “update” button your post.
Notice there’s only a “reviews” box at the bottom of this page? (This is where reviews can be recommended)
