I'm wondering if you guys have a firm schedule for how often you release lessons from each level? I ask mainly because although I'd be interested in signing up for the advanced series (love the 东北话 lesson), they seem to be fairly few and far between. I know this kind of question about the advanced materials has been asked before, but I was hoping for some updated info (please).

I'm also on the go a lot, so the annotated short stories aren't really much help there. Hopefully your new HSK app will be good company!
