I usually view the site using the “Categories” screen. I notice that most areas tell me if there’s been a new post, but the Classifieds does not. I think we’d get more action there, if there were some kind of indication that something new had been added.
Done! I forgot I had removed this column back when it just showed the amount of views, no I have it set to show new/unread without the views. If you want to be notified when there’s new posts in classifieds you could turn notifications on for this category. Depending on the level notifications you’ll either get a notification just on the site, or you can have it email you when there’s new posts. Watching first new post would be a good option for this.
