I'll just second this whole thread, especially the latest post.

The advanced lessons don't teach anything and are just pure listening practice. Ok, they aren't bad, but you can get this kind of listening practice anywhere very easily. What's important for teaching is to actually... explain stuff. This is done very well in the beginner/elementary lessons, and if you could find someway to do the same for intermediate/advanced lessons... without being too simple somehow, it would be perfect.

As for subscribing, I want to support your cause too, but no offence but nobody in their right mind would subscribe to this site in its current state. A one year subscription costs like $50USD, yet there is barely any content worth paying for here. Even if your beginner/elementary lessons are pretty good, anybody studying seriously enough to be willing to pay money for the subscription would expect to be bored of beginner/elementary lessons before their subscription finishes. If you don't have Intermediate lessons coming out on a timely basis, what's the point of spending money on a subscription then? Surely people who subscribe would want to improve no?

Advanced lessons don't count period because they aren't lessons.

Yes, this is more whiny nagging, but I do think this site has a lot of potential, you just need to fulfill it!
