This is done. If you want people to see all your daylilies, you can give them this page:
http://garden.org/lists/view/b...
Or just tell them to select "Hemerocallis" under the "View only genus" area.
Also, if you want to delete other categories, it turns out that you can do that without my assistance. Just click on "Manage categories" on the left hand side of the screen and you'll see where to delete them.
