I don't think most of the people who post pictures are doing so to learn for the sake of learning. They want to know how to sort what they have before making a shipment to Boardsort.
If there's got to be a section like this where members like OP take a lot of time posting photos of components, 1) Someone from Boardsort should answer, and 2) There ought to be no guessing, since any answers given might be treated as the gospel truth by who knows how many other people who might not post here at all.
Ignoring questions is a disservice to everyone involved, and if the reason for that is lack of time/staff, then this system is the wrong one to be using (and I can tell you already that it is). My
last post had one answer from a member with 10 posts, and I already figured out one of those answers is wrong....we need something better here, and I only say that because I'm a fan of Boardsort but a frustrated one, too.
