Hmm, you can't fix a users lesson for them?
Technically I could but I wouldn't because a) I am not expert in every language; b) I looked at this particular lesson (well, I know Russian and Englihs) and it doesn't seem to me too bad; c) if it was too bad I would simply make it private.
One more thing, I was thinking of putting up a lesson, but you say
user lessons can't have sound?? That is terrible in my opinion, listening
to the correct pronunciation is very important, at least to me.
Yet. We have in plans adding this feature.
Hmm,
maybe if the users can't put the sounds in, your team can add the
correct sound to the users lesson?
It would be too difficult. Don't think of us as a huge corporation with lots of staff. We are just a group of enthusiasts that create this site at our free time.
It's better to give a way to add sounds to users themselves - sooner or later we'll add this feature.
And rest assured that we are dedicated to constant improvement of the site.
