"OK" and other acronyms / short forms of "Yes" and "No"

[n-regen]

Kaltxì, ma frapo!

I know we already have a topic about leNa'vi acronyms (like OK, BTW, WTF, ...) in another sub-forum, but it would be great if we had some officially approved ones - especially common ones like OK etc.

We also need short forms form "yes" and "no", because using two-syllable-words for something so common doesn't seem very sensible.
(some people already started using "sra" and "ke", but a official form would be great)

We do have OK. It's tam.

There is nothing that unusual about two syllable words for "yes" and "no".
