I liked the video a lot, Dave! ... you flatterer! It covered the basic process thoroughly, clearly and well.
I thought you could have punched up even more how only NGA has this cool tool, but you did say it. I guess if any viewer makes the mistake that you were just describing how MOST seed swaps work, they will be disillusioned as soon as they go to any other swap, anywhere.
NGA - accept no substitutes!
Maybe, if YouTube videos on seed swaps seem like a good way to advertise for NGA, one of the gang could make an "advanced" swapping video that was really more about adding new cultivars to the Plant Database. Perhaps call it "How to trade seeds so rare and unusual that no one you know has heard of them before".
"Seeds SO rare that they are not yet even in OUR database! But you can add them, through consultation with our team of plant experts."
