On my NFL football blog all users are allowed to make blog posts. New registrants are given contributor status. When users make a post it is reviewed by an editor, then the editor schedules the post to publish at a time fitting our blog schedule.
Multiple editors have asked me if they could make a comment on the article right after they edit the post and schedule it to be published, but before it is actually published.
By comments, I mean comments on the article content, not comments to the contributor about their writing style, grammar, spelling, etc. or comments that other editors can see in the backend. I use Peter's Post Notes and Peter's Collaboration E-mails to handle communication with contributors about these issues/situations.
What I need, example: A contributor writes an article about Peyton Manning signing with the Denver Broncos. The editor is notified at 10pm that the post has been submitted for review. He/she goes in to check the post for grammar, spelling, tags, proper category, etc. The editor makes all the necessary corrections and schedules the post to publish at 9am tomorrow. Now, the editor wants to leave his thoughts about Peyton Manning's contract with the Broncos for the world to see. The problem, the post publishes at 9am tomorrow, but he is reading the post at 10pm today... and does not want to come back 11 hours later to leave a comment on a post he is reading right now.
This makes sense to allow the editor to comment before the post publishes, since the editor has already read the post, so I would like to make it easier for editors if possible, rather than the editor needing to come back once the post has published to make their comments.
I really have no preference as to whether the timestamp on the comment is the same as the post publish time or the time the comment was actually made, even if it was before the post was scheduled to publish.
I found a forum post that is two years old ( http://core.trac.wordpress.org/ticket/11810 ) discussing a vulnerability in WordPress that used to allow comments on unpublished posts, but I simply cannot find a way to allow Editors to leave comments on unpublished posts in WordPress 3.
