The selling system is separate from your collection
I know that the Marketplace is a separate section... that's not my question.
Why is there a "For Trade" check box, but not a "For Sale" check box?
Maybe the question should be reversed... Why aren't trades part of the BGG Marketplace? Shouldn't items available for sale and/or trade be found in the same place? What the hell are trades doing in the Game's area in the first place?
