Hi and thanks...I was hoping someone could clarify this.
Also, my "Hot Threads" have been down for a couple days. It just says "no row returned" or something like that. No big deal, just wanted to mention it.
New Posts only gives you a list of most recent posts made. Activity Feed gives you four types of content to view with the option to filter to exclude and include.
The Hot Threads issue was found yesterday and is being worked on. :)
