Communists on the moon !

Ok, I see what you and SJ are saying now Juri. Actually I wasn't talking about moving the base to a different orbit, but causing it to tumble, wobble etc, which would make docking difficult. I thought that's what Loser was saying too, but I reread it and see he was talking about actually changing position in space, so I was incorrect when I supported his point there. Movement of people around the inside won't cause the base to move to a different location, but it can have a minor effect on the orientation of the base, as demonstrated by the skylab astronauts. But as I was saying to Loser originally , even that effect would be infinetesimal when dealing with a base as large as what would likely be placed at an L4 L5 point.
