I think it would be really cool if you could pin guestbook posts. The pinned post would stay at the top of all of the posts. If you wanted to add a little message to your guestbook and keep it so everyone could see it without having to scroll for it, or if you just wanted to pin someones post because you thought it was funny or sweet or something. I keep wanting to do this and then I remember it's not an option, so I had to submit a ticket haha
