Thank you. Very very pleased that Angelika's English is good, without too much of any kind of accent. The narrator for webinars a few years ago was totally incomprehensible and impossible to follow. But Angelika's choice of words is sometimes incorrect. She uses the word "check" when she actually means "tick". "Check" means to verify/to ascertain. The little V symbol you insert into a box is called a "tick" (verb: to tick/tick off). Also I would use "permitted" and "prohibited" instead of "allowed" and "forbidden", although the latter terms are not actually incorrect.
The little V is a "check" or "checkmark" in USEN. To "tick off" is to cause someone to be angered in the US. I have a series of articles contrasting US and UK English on my blog "Words of the Law." You should check it out before criticizing others.
