Over the next few days you will notice some changes in some of the buttons and the navigational aids being presented within the Premium section.  This upgrade may cause some buttons to seem a little off (cosmetically) while the upgrade is being completed.  Rest assured that when I have finished, the Premium section should be a LOT easier to navigate based on feedback I've received from users like yourself.  There will also be some cosmetic changes to improve your Chinese learning.  I'll specify the details when it's complete - hopefully sooner rather than later.
