I made it a few years ago, when I liked the Avatar show... I honestly can't wait until the sequel, if not just for the mind-blowing visuals! ... Yes, I actually did try to learn the language, ! While that failed, it helped me in many ways over languages and specifically, core semantics, that I did not anticipate. Needless to say, it really is helping me getting over my bloody stroke, and improving my overall mental abilities. Now, if I ever try it again [my curiosity will lead me to it], I will learn a real language, rather then fictional (Avatar-based).
