Thanks, Chelle, I do have 6 kinds of seed listed there.
Can you see them using this link? It says "this is how others see your list".

P.S. One way I envision this working is that someone sees a seed I have that is NOT in the "for postage" category and asks for it. I would be willing to trade that "cherished" seed if they contribute to a general pool of sharable seeds.
