I just deleted my all trust list personalizations and going to start again.
Why, I'm not sure, but my brain just melted a bit and I want to think about it.
In view of the small number of members who actually set their own list, then I guess the vast majority will be seeing red and green trust by default left by these DT1 and DT2 members

Is that right?
