Merit was starting to get boring, so we had to have a new hot topic. We also have a new category of DT source. TMAN made me a DT2, so he must be a DT source. It isn't quite like merit though, he doesn't get his DTs renewed every month.
What's the difference between a DT and a DT2 exactly? Isn't the default list one?
DT (DefaultTrust) consists of DT1, DT2, DT3, etc levels.
DT1 users are selected by algorithm. They can include other users into their trust lists - those users become DT2. And so on.
Default setting is to see ratings posted by DT1 and DT2 members as trusted (i.e. making trust scores red/green). Users can change the default to a different depth (e.g. see only DT1 ratings as trusted) or to alter or even completely replace DT with their own list of trusted users.
