Yikes – just visited the Mac site (as you do) and discovered that our Glossary of tech terms is up there!
The site with info on the book is: Macmillan English
The 2-page Glossary of terms (like audacity, infinite cloner, LAT, VLE) is a free downloadable .pdf and would make a good handout at the end of a training session.
As they say oop norf, Take That.
