Nisus Writer Pro 3.1 (and Nisus Writer Express 4.1) were just released and added several non-English localizations. We are interested in adding additional translations, so more people can enjoy using Nisus Writer in their native language.
If you might be interested in helping out, please let us know. You can contact us any way you like, including an email to the following address:
This is purely volunteer work. We aren’t able to pay for the translation, sorry.
