Spike, that is weird! I see it in Beans, Hot Peppers, and Vegetables, but for me it doesn't show up in Growing Tomatoes, Round Robin or Seed Saving ( I don't find a Seed Exchange anymore.) I thought there used to be a seed exchange as a subforum to Growing Tomatoes, but I don't see it there now.
Houzz has not made it easy to find things easily, and so many pop-ups offering their services get in the way, some with no X button, so end up closing the entire window to get out. I only check in about once a month.
... Whoa, I take back there not being a Seed Exchange, it must have come up on a tab I was searching and didn't close. Looks like it's part of More Forums/Exchanges and Trading/Seed Exchange. But I don't see your post there.
