Well, the new Web site has been up for about three weeks, and I have heard a lot of useful feedback, specifically on what teachers and students find most useful for their learning. One of the projects that is almost complete are the ESL Vocabulary Quizzes HERE that people have enjoyed over the years—about 350 of them!!
I have also been adding into the lessons the idioms section that teachers and students found useful, and you can see these near the topic of most listening activities.
Feel free to contact me if you have more questions or ideas.
