A note about "TCM..." posts

These posts are derived from class notes written by the teacher. They are shortened versions of the notes and only include the parts that I need to study for the tests that I have every two weeks in this course.
Very little , if any part at all, of the posts beginning with "TCM-Functions of ...." have been modified by me. They are the words of my teacher, Valerie Smith.

(just to give clear ownership of those posts)

Everything else- The different points on the channels, and my rants and complaints, are fully written by be.

Thanks for reading.
