Haha, thanks Jean-Michel you alerted me to the problem. Even though I had tried making changes to the strings in that document I never saw the changes to the text. I was even clearing my browsers cache and nothing.
But then you mentioned purging the cache in Moodle, (1.9 didn't have this) and tadahh! It worked. I can see the changes.
So I guess the documentation is not exactly wrong, but those three lines as mentioned in the doc. are not all together in 2.3.1.
Thanks
