Bungie - theres a shit ton of space between the postmaster and special orders. Put a NPC broker there to administer weapons and gear trades between friends or clan members. Its ridonkulous why some ppl have 2 Ghorns like me, and others have multiples of other exotics, when we could trade gear of the same class. Hell... I'd gladly give up some of the materials to boot as a fee (like Eris with the Black Wax).
