I find your german lesson very interesting. I think learning the culture is also very important to german language lessons. You understand the people better.
I find it funny that i can't just pay my 10 USD once for monthly premium subscription and then when the month is over I will decide whether to continue or not.
Please be transparent!!!!!!
I agree that's annoying (I'd sign up for advanced account if it was paid monthly) but I'm pretty sure you can take a month's free trial to test the features in the meantime.l
