At the bottom of the private topic is the following:
"Delete".
I've always assumed that Sara had the authority to look at private post. Maybe I'm wrong.
Regarding views counts:
1) Everytime they are viewed, even by the same person, the count increases.
2) When you post, you get a confirmation of your post. That confirmation appears to add to the count.
3) Editing a post, you get a confirmation of your post. That confirmation appears to add to the count.
4) When someone posts, the view count for that post is updated.
5) There appears to be a batch job that periodically updates the view counter without requiring a post. You can see that happening in the "News and Updates" forum. Since only Sara posts there, and since some of them have only the original post, you can see what's going on. In fact - look at the first 2 topics in that forum:
#1 - 0 replies; 0 views; 1/28 post date.
#2 - 0 replies; 235 views; 1/24 post date.
Maybe someone has a better explanation for 5)?
