When I looked up kiva in the dictionary, it said, "An underground or partly underground chamber in a Pueblo village, used by the men especially for ceremonies or councils," and its etymology is from the Hopi Indians.

We used it to describe the format of a conference. The inner group were the presenters, and they could share among themselves. The outer group (where I was) were the "elders" or "wisemen" who respond at specific times. Has anyone else used this kiva format?
