How do I make it so a people who aren't logged in can't view threads?

I want them to be able to see the list of threads but I don't want them to be able to see what's inside the threads until they login.

Any ideas?

Admin cp - Usergroups - Usergroup Manager - Unregistered/ Not Logged in - Can View Thread Content - No.
