When it has passed review, I suppose we could set up a few wikis at prototype.wikimedia.org and test it there. It was originally set up for the usability initiative but it seems to be used for increasingly random testing purposes now, and we have no other proper place for this.
Just curious: There's also http://test.wikipedia.org/ . What's the difference between it and prototype?
I know that prototype has different language versions and i'm not sure about test in this regard. And except that?
Test is a part of the cluster. Prototype is not. We have more flexibility on what we can put on prototype versus test.
