Hey, I just noticed that the default date format (displayed when not logged in) is something like MM-DD-YYYY,
which is completely confusing (seems to be a US american date order, but with - instead of / ).

I suggest to change the default to the internationally understood
YYYY-MM-DD
(international ISO date format https://en.wikipedia.org/wiki/ISO_8601#Calendar_dates )
