Okay, that makes sense. And how do I see who is on the DT1 and DT2 lists?

Go here: https://bitcointalk.org/index.php?action=trust, remove everything besides DefaultTrust. The list that you see below is the list of DT members.

My trust bar is green, so I am assuming I am on one of those, but how can I check?

You are not. You just have ratings left by other DT members.

I see so even if I give some positive trust rating to someone it won't actually make a difference to their bar right?
