I have an account in Taiwanese/Holo Wikipedia
(http://zh-min-nan.wikipedia.org/wiki/Th%C3%A2u-ia%CC%8Dh) and I'm a sysop of
Taiwanese Wikisource. Formerly we've used the code "zh-min-nan", but now we're
in the ISO 639-3 (http://www.sil.org/iso639-3/codes.asp?order=639_3&letter=n)
list, using its code "nan". We want to have our code more formally and briefly
and change it in to the new one, but we don't know how. Can you help us or tell
us what to do? I've asked User:Angela and User:Tim_Starling in Meta-Wiki, and
Angela suggest me to report here. Please help us! Thanks very much!
