What's in a Name? The Many Names of the Ancient Astronaut Society

I was trying to do some research into the organization run by Giorgio Tsoukalos, but I will be damned if I can figure out what they are calling the thing these days. Ages and ages ago, when Erich von Däniken co-founded it with Gene M. Phillips in 1973, I believe the organization was called the Ancient Astronaut Society. For a long time its successor was called the Archaeology, Astronautics and SETI Research Association, and that’s how it’s still named on Tsoukalos’s Legendary Times website. But over at his sister site, Legendary Times Books, the organization is called the Ancient Alien Society.

Worse, there is another web page, apparently an incomplete template for the same organization, calling itself the Ancient Astronaut Society in its logo but the Ancient Astronauts Society (with the plural astronauts) on its pages.

All of these offer the same subscriptions and membership info (including the word-for-word same text about membership and benefits), so they all seem to be the same thing. But how is it that the ancient astronaut organization can’t manage to get its own name right? Is it possible that Giorgio Tsoukalos is so careless with the facts that he did not pay attention to what his own web pages call his own organization? What does that say about ancient astronaut theorists' ability to get the facts right elsewhere?
