Starwars.com had a n Arubesh translater thing in a download or printout available under the clonewars section.... for kids under an activities section a few days ago.
Had the alphabet and numbers and some others like period and question mark and hyphen and such. I dont know about a program where you type it and then it is converted entirely to Arubesh.
There is also something along the same lines for Mandoa. not so much an alphabet, but a grammar and language dictionary type thing....
I think that was from a Karen Travis website....
