The past year has been a good year for the Hawaiian language on the web. Google made Hawaiian the first native American language to be officially supported, Wikipedia has Hawaiian language articles and thanks to Hawaiian language support being shipped with OS X, its a lot easier to write ʻŌlelo Hawaiʻi :-) How do you say world wide web in Hawaiian? Pūnaewele puni honua.
You can upload a Hawaiian font keyboard remapper from these folks - http://www.olelo.hawaii.edu .Itʻs a bit friendlier than "special" characters in Word when youʻre writing. ( alt + vowel = vowel with kahako ).
