where are you seeing those? I have seen NO tips and notes whatsoever for the Swahili course. In the beginning they had them in the Vietnamese course, but unfortunately they did not keep up with them. It would be EXTREMELY HELPFUL if there were such a thing. I am just having to make deductions as I go along.
P.S. the link you gave me just took me to my home page. There were no tips and notes or tips or notes there!
