@sulurph, wanted to make sure you found your way to this thread! Please let me know if other gardening friends are coming with you. They can come to garden.org and use the seed swap tool or bring/find seeds at the swap. It's also fine for you to make some dibs on their behalf.
So far, I've had 1 response to the tree-mail invites I sent out. Since replies are seen by all recipients on the tree-mail blast, I encouraged people to just come to this thread to let us know if they're interested. I did want to give a couple of weeks for word to spread before opening trading on the swap tool.
Meanwhile, go right ahead and list seeds! You must have at least one item listed in order to request seeds through the swap tool.
Like they used to say in culinary school, "If it isn't green, it isn't seen!" so remember to click that button next to each listed item so it turns green (and shows up on our swap).
You can put items on your wish list now, too. Once trading begins, use your wish list to jog your memory so you can put dibs on your most-wanted items. (Wish list items aren't automatically dibbed for you when trading starts.) Each "ticket" you get lets you "dib" or claim an item.
