We had a very interesting question about an old translation. I posted an answer which was partly inaccurate, but then I received a lot of good suggestions and I was able to combine those into a fairly authoritative answer.
This was a collaborative effort, yet when I tried to convert to a Wiki answer (twice!) by checking the box and saving, it did not take. Did I do it wrong?
Is there some kind of restriction on Wiki conversion i.e. time, number of edit, etc that prevented this?
