How can you tell? Is there a way of viewing people's trust lists?
add a user to your trust list and you'll be able to see it clear as day. you'll have to exclude DT and remove other users.
Can you give more details? Where do I see it? I've added users to my trust list before and not noticed their trust list appear anywhere.
Edit: oh, are you saying I should wipe out my whole trust list other than 2 entries, just keeping in the person I want to examine, and ~DefaultTrust?
