You can now mark the geographical location of listings within the marketplace. This especially helps people that want to trade plants or seeds locally within their communities. It also helps to define where a package of seeds is being shipped from if you are mailing seeds to someone.
Another feature is that we have a global map page that shows all of the listing in the marketplace. Plants do better in environments that they have acclimated to, so trading for seeds or plants near you will result in having a healthier plant.
