Is there a special way to create translations or can i just copy the en file to a desired other language and start translating the strings?See here:
http://webmin.com/modules-newlang.htmlAsk questions whenever you have them. We
love translations.
Note that Virtualmin has quite a bit of language text hidden in the Virtualmin Framed Theme directory, as well (virtual-server-theme). Same directory structure and file format, so nothing tricky. Some folks just don't know that themes can have languages too.
