I've already said the journals will not be moved back. There also is a way to tell if a subforum has a new post rather than the forum itself.
This screenshot shows you what the difference between a subforum with no new posts and a subforum with at least one new post is. If you see the red such as in that one, then the Journals section must have a new post. If the All About You! forum is red but the subforum icon doesn't have the red around it, you know that there has not been a new post in there.
As for the Pet Stats, I don't really see why they wouldn't be very fitting under zoo pens. You keep your pets stats in your zoo pen. If by some chance you miss the subforum originally, you'll catch it when you open the Zoo Pen forum. It's large at the top of the forum and thus pretty hard to miss for any new person making a pen. It's also not something that we
make people post, so I don't think it really
needs to be a main forum when it fits so well under one.
