Chris and Mary,
I think this is an issue HQ should address. It should either work fully or be turned off until it can be. Or at the very least have some warning.
Since an important part of Moodlecloud's mission it to allow people to try out Moodle, for every person like Enrique who reports the issue, many people will just think it is the way Moodle works, never look into the issue, and so get a bad impression of Moodle as buggy and unreliable. And language customisation is one of those features where Moodle really stands out, it is done so well.
