Since I just posted about the new Hakka-based Chinese character input method I would be amiss not to note as well the release early this year of a different Chinese character input method based on Taiwanese romanization.
This one is available in Windows, Mac, and Linux flavors.
See the FAQ and documents below for more information (Mandarin only).

I know Minnan is an occasionally politicized term, but I”ve been following the MOE on this since Chen’s administration first started, and the use of Taiwan Minnan has been a sort of consensus policy since I guess 2001. I believe because in this case, it’s use is only descriptive, not political.
