Thanks, gazumped. Getting a clear answer to this question has been remarkably difficult. It seems that adding notes to Evernote via Email is legal, highly useful and allowed. But it is also a subject that, technically, appears to fall through the cracks as it is not really a developer level question.
My best bet, I think, would be to ask someone who works for or with Yinxiang Biji in China and this would need to be, for me, a dual Chinese/English speaker. If you have any thoughts, I'd love to hear them.
