I seem to recall hearing from someone (I think it might have been Dan or aaa, when I met them in Cleveland) that there was some talk at one point of making a system for the Goods For Sale/Trade board to identify who's safe to do business with, but it never really took off, and was deactivated.
My guess is that when Dan reactivated the Karma system for use in keeping track of the main site deals, this "verified" thing came back with it. I suggest we should indeed go forward and implement this for the GFST board (since it seems like a pretty good idea). Maybe BAHayman can chime in if it's doable...
So... who are the lucky guys that you saw "verified" by? I don't see it by anyone...
