This course is a fabulous way to learn a language. Adam is an enthusiastic and knowledgeable teacher who has used his computer programming skills to present an entertaining and reasonably priced course. He has truly leveraged the internet to present a variety of teaching aids, such as being able to choose translations, Chinese characters, or pinyin - with a mouse over effect of getting 2 of the 3 possibilities. So if you choose Chinese characters, placing the mouse over the characters will provide pinyin as a highlighted callout below the Chinese characters.

I think your course is well organised and is great for beginners as well as more advanced. I've only listened to about 30 lessons so far. I like that at any time I can review lessons. It's also great to be listening to native speakers. Unfortunately there is no short cut to learning a new language especially when it comes to tonal Asian languages. Conversation context is great.

Seeing the pinyin makes a big difference. I like to picture it in my head when composing sentences and having the tones works helps a lot. Your product is great! Especially now I can visualise the tones.
