First of all I have in mind the help .html files. But I edited a few times the .pot files, I could do that, even if it’s not my cup of tea.
The problem with translating options, is that sometimes it even sounds ridiculous in other language and some non-english speakers could miss the real meaning of it. Maybe it could be an idea adding the translation in brackets aside the english words. Don’t know if this is ok with wordpress guidelines. I will read more about it.
Another issue is all these could last even a week working time. So… are there any perks for it, a free licence maybe ?
