The first question is: What does "Tero Danco" mean?

It is a composite of two of my favorite joys: "Earth" and "Dance."

Many of the variations of "earth dance" were already taken, at least in English.
So this is "EarthDance" in the Esperanto language, a language that was constructed
for the purpose of facilitating communication between people who have different
first languages.  "Esperanto," by the way, means "one who hopes."

That's all for now... Spend some time today in living your joy!!
