That's great news. Please bring back the previous payment plan so we can sign up for Premium. 10/month is too much for teachers who want to teach for free and help bring the site students.
In China, pay is 1/3 to 1/4 the amount compared to the US. This is due to the low costs of items and services in China. For example, a bottle of coke is less than 50 cents in China. You can get a dinner with something to drink for $2.50 cents (beef with noodles, after 3/4 of the meal I am full). In the US, it would cost easily $20 at an Outback Steakhouse.
Happy Holidays
