I have gotten Personalized Catalog Views to only show the desired items to each specific Web Store user, but I'm having trouble getting it to hide items from users that are not logged in. Is the way to do this simply to prevent anyone from browsing the web store without logging in, in the first place, and that's why there doesn't seem to be an option to hide all items from anonymous users? I see I don't have my Customer Segment defined properly though. I'll take care of that first before saying I'm stuck. UPDATE: That was the problem: The Dynamic Group that the Customer Segment was based on wasn't set up right. It's not showing those items only for the customers in that Group, and not for anonymous users at all. Just like I wanted. 🙂
