As from 11 April 2008 we have started using placeholders to allow commenting to start before a full post is published.  This will help in those situations where a blogger only has time to post late in the day. This is how they work:

• Either a full post or a placeholder will appear  by 3.30pm. That’s your cue to start commenting. If a comment is made on another post asking after the whereabouts of either the post or the placeholder it will be deleted.  The same goes for questions/comments about clues for other puzzles.
• If a full post has not appeared by around 7pm-ish, it will be considered fair game for anyone to post a blog of their own - I will edit the placeholder at the time to confirm this. If you’re not on the blogging team then your blog will have to appear as a comment but this has happened a couple of times in the past and it seemed to work ok. All I ask is that if you plan to write something of your own, you let everyone else know in a comment so that we don’t have more than one person writing about the same puzzle.
• This will apply to all puzzles, not just the Guardian.
• That’s it.

The page originally appeared as a post here, which is where you can comment, should you wish to do so.
