KOffice uses the same dictationary files as OpenOffice.
This means that if you want German(or any other language supported by OO), simply replace the included dictationary with the one you use in OpenOffice.
Here you have a guide on how to do it: http://translate.google.com/translate?sl=no&tl=en&js=n&prev=_t&hl=no&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fwww.dinside.no%2F878443%2Fnorske-ordlister-til-kingsoft-office&act=url
Does this work also with Spanish? And could I have Spanish and German and English at the same time? Or does Kingsoft only work with one default language? The thing is, I´m German by myself, but I live in Mexico and because I am working in translation, I would like to have this program working with all the three languages. Is this possible? And if yes, could anybody put the link (links) to download all these languages? Thanks in advanced for helping!
