I am currently working on a Latin Textbook (Wheelock's gives me tons of students to tutor but I'd rather they be able to learn from an awesome textbook/teacher).
What I would like to know is:
1. What do you find lacking in your textbook? (and, of course, which book are you using?)
2. Which parts of the Latin language do you find most confusing?
3. Are there any areas you feel aren't covered in-depth enough ...
