The most wholesome lesson ever.
As klingon is somehow case sensitive, shouldn't the sentences start with "muSaH" not with "MuSaH"? Here in the discussion it is shown correctly, but in the actual part of the lesson it is not.
Yes. In certain circumstances the software automatically recapitalizes. It is not an appropriate behavior with Klingon, but it would take significant rewriting of the code, so I don't know when, if ever, we'll see it fixed.
