Heh heh, looks like DT3's a cool place to be, look at the company I'm keeping....
and I don't get outraged scammers inboxing me with abuse for Red Tagging them (not very often anyway, unless they've checked their "junk" untrusted feedback)
And just to confirm what I think is so: If you go to
Trust summary>Trust settings>Trust depth (max 4)
and change the default from 2 to 3, then all the feedback that DT3 members have left will appear (for you only) as red/green numbers under the appropriate profiles and in their "trusted feedback", just as Levels 1 and 2 do by default setting?
maybe instead of saying you're basing these ratings on "Marketplace Trust System" you could say something like "Trust lists", or "Trust Hierarchy". That's just my two cents, but if all of this information is available for everybody within a couple of clicks, how is it helpful to post it in thread format?
As far as I can see, it's just an easy to read summary of the hierarchical version of the trust network which as you say, is available within a couple of clicks, but also rather opaque (to me anyway).
I don't think OP's trying to set up a "Trust Fork" or reinvent the wheel, from what I can make out.
