I am very happy to get in touch with Yokoyama-san. He is an Ainu and Klingon expert. He is also interested in Ryukyu (Okinawan) language. What a coincidence!
He is the author of the following pages.
Introduction of the Ainu Times:

How to use Mac OS X 10.3's IM "Koto-eri 4" in Ainu Mode:

And this page.

He is a member of The Klingon Language Institute.

(the link to www.kli.org is now somehow broken)
He tried to translate some OpenOffice.org menu in Ainu: (temporary)
File - iyop
Edit - a=utaoke p
View - inkar
Insert - a=i=oputuypa wa a=i=payere
Format - kanpinuye
Tools - a=eywanke p
Window - puyar
Help - ikasuy
I think we have made a small step, and we can start and go forward.
