( This list can't possibly be a complete one, but it's something to get started on. Do the Shakers count as a utopian community?
Robert Owen's New Lanark?
And all those millenial cults of the middle ages? )
Don't confuse a utopia with a commune.
Utopian ideals are also not the same as a Utopia.
As long as we have sewers that have to be unstopped, we'll never have a utopia.. (hmm. might make a nice .sig )
More's Utopia even mentions the conveniences. Of course, in his day, they were chamber pots made of gold....
