And I want to insist on my suggestion regarding trust:
guest should see some trust. Default trust would make sense but any trust. Non registered users
are still being scammed by known scammers because they don't see the tags.
I'd also like to see trust on all boards that show signatures. I'm mainly thinking about user
Velkro, who advertises his scam site in his signature and mainly posts on boards that don't show trust ratings.
I'll add another tag, but that doesn't mean anything as long as it's not clearly visible wherever his signature is shown.
Between this post and my tag, he got tagged twice already

My
Reference link points at a scam accusation by minerjones. He hasn't tagged this user yet.
Beginners & Help should show trust ratings, it's terrible idea not to warn Beginners!
