Unfortunately, site interfaces in the following languages are going away in the update of the software I must use (phpBB3.2.8 ) to continue maintaining the site:
Magyar/Hungarian
Svenska/Swedish
Español Argentino/Argentinian Spanish
Nederlands (Formeel)/Dutch (Formal Honorifics)
In the case of the latter two, this is no great tragedy, as you can still choose Español (Usted), Español (Tú), and Nederlands (Informeel). But it's frustrating to see Swedish and Hungarian unsupported.
In addition:
Čeština/Czech
Suomi/Finnish
עברית/Hebrew
....will have language packs that are out of date. So they may function, but they may have some problems for now.
It is of course, my hope that eventually the pbpBB software will support these languages. If this is a project that appeals to you, I recommend contacting the phpBB community boards:
