How does the Trust system work?

[W-M]

Hello,

I am slightly confused about how the Trust system works: When do good/bad ratings I gave to other people show up on the numbers below their name? And what exactly do those numbers mean? And what is the threshold for when is a person's trust changed to green resp. red?

Thank you very much for your reply. You managed to explain it perfectly.
