My mother has a MBA in linguistics from the University of Jerusalem. She retired from teaching and currently does translation work. I asked if she was interested and she said she'd be happy to help out free of charge, at my request.
I'm not sure how to edit patch files, though (and she's definitely not going to do that part, LOL). Is there a program I can use to easily extract the text and replace it? If not, you might have to extract it yourself and send it to me together with any limitations I need to be aware of (i.e. character limits, etc...). I would then send you the translated text once I have it so you can add it to the patch yourself.
