You can become Na'vi if you join secondlife. secondlife.com We have entire regions dedicated to the Na'vi way of life and full role play including weapons and battles with the sky people. There are translators you can access that use the Na'vi language and translate it to English as well.
You will be amazed at the similarity and realism there. My Avatar there looks like jake and I have a life mate there as well. come join us. Let them know Romanza Pomilio sent you to Second life so I get credit for you signing up. In return, we will be glad to help you learn the ways of the Na'vi and setting up.
Have fun, hope to see you there. (See my pic at the left as jake, Na'vi ;-)
