I went to the profile of some users and clicked on the trust system and found that they got green trust and some of them have red trust.
I needed many months to realize trust, trust feedback, what they are. It is interesting to see a pure newbies immediately fall in Trust, Trust feedback.
And go to my account and see there is a post a new feedback and trust settings options. I really don't understand these things can someone give me some details please?
Guides are above but as a newbie, you don't need to learn about it first.
Learn about Bitcoin as it is more important for why you are in Bitcointalk forum.
Next you can learn forum rules as you can be banned by breaking rules.
With Trust, trust feedback, if you don't trade with other members, you don't need it. You will not be banned by Trust or Trust Feedback. It is less important than forum rules.
