Dear WW: I'll have to do some cogitation before I can use that site. I don't know enough to ask the right questions.
Incidentally, those sweet gum burrs (I think that's the word) threaten to make me take a tumble, now that so many leaves have fallen and they are hidden. I'm so unsteady on my feet because nerve injury from collapsed intervertebral disc and just plain stenosis (narrowing of places where nerves exit spine) that I lack sensation and strength in my lower legs. I wish the squirrels worked harder on them. Before so many leaves fell, the wind would roll them off the pavement. But now they get trapped under the leaves.
