Hi guys – If you've recently tried to write a comment and it didn't come up – the reason has been identified and rectified. I'd updated my editor and it created a nice, new editor for the comment pane – complete with the ability to customize the fonts and so forth. But it also apparently caused the comments to disappear once they'd been submitted. Poof! All gone. So I never even knew they'd been submitted.
Luckily, I was just made aware of the problem and corrected it by replacing the new and deimproved editor with the older version. So if you've commented and are wondering when your comment will appear – it'll be never unless you resubmit it, unfortunately.
