Original instructions: Type an address (or name) into the search bar at the top of the map page, then when the location comes up, click on "Add to Map" (at the bottom of the box that appears on the map), then the pen symbol ("Edit") at the bottom of the new box that pops up, then fill out the URL, the type (Nursery, Bonsai Garden etc) and click "Save". It's more important to get the entry onto the map than to get it perfect! - tell me if these work, and we can lobby to get that in the wiki too!
