Ah, might not be as bad as it looks. Just edited said post but I got the No Permissions page - which is interesting as Guests do have permission to post there. Maybe because Guests can't edit their posts? Hmmm. I can't see how it would know who the original guest was, so I'm guessing in spite of the edit button and box coming up that Guests posts can't be edited via the quick edit? Cool. Be amusing to watch people try.
