This is incorrect. Leaving positive trust for another user if you are DT1 does not make them DT2. This is achieved by adding their name to your own individual trust list.
Yep, that's the first thing I noticed, and I misunderstood that for quite a while before being corrected by Lutpin a while back. OP is certainly correct that there are a lot of misconceptions about the trust system, even among older members--and that's not surprising, since it is a bit complicated.
Explaining everyone the implications of the forum trust will make it possible to wipe out a good bunch of strife on the forum.
I applaud your effort here, SebastianJu, but I disagree with the above statement. Though a lot of members really don't understand the mechanics of how the trust system works, I seriously doubt educating people is going to reduce strife. Why? Because most of that strife stems from jealousy, resentment of authority, and hard feelings because of negative trust received by DT members. No amount of education is going to eliminate that. I'm confident members like cryptohunter, Thule, and that bunch of trolls know how everything works, and they're going to keep riling everybody up no matter how many tutorials are posted.
But again, this is a good effort on your part and should help people understand how the system works. That in itself is a good thing.
