I am trying to figure out how to force commenters to use threaded comments (and not the general comment box at the bottom of the post) on one particular post. I want only admins to be able to post new top-level comments and to force all other users to click the Reply button under the comment to which they are responding.
I've tried using CSS to hide the comment box or to accentuate the Reply link, but it's not working. and it's a terrible hack anyway.
I'm using WordPress 3.8.1, and unfortunately don't have the ability to add plug-ins due to being on @%^&%#^$@# managed hosting. Thanks for any tips or tricks.
