Nope, but i'm in the process of doing so. Got a fair wealth of material i'm knocking up with the intention of getting published. The aim is to make stuff very easy for new and utterly inexperienced teachers, and all of it productive oral practise. But it ain't gonna earn me a penny, it'll get copied and sold on Taobao for pennies. Keeps me busy though.

i only sold some powerpoint games to a center but not really published. for what you even should do that only that some retards copy your ideas
