A good product! Only one thing just happens to me that I can't translate it because the keys are missing in the polyglot form? Do you also plan to include an option that prevents those under 18 from monetizing?
As far as as I now problem with language have been solved and all keys are their places now :)
About age limit for monetizing: We have no this ability in our task list, but will take it into account as option for the future versions.
