Thanks for your post. Regarding your question, yes I did, mostly younger learners. I am teaching nearly 20 years, not only English, mostly engineering. As I am non-native, sometimes I battle to find the right resources for my students, so I dislike a to structured curriculum what you have to follow. So Mimi's idea is not to bad to look for some kind of guideline to carry with, but I hope she would not be to stuck to it.
