First, many thanks that you have this intention. We love that so many of you are asking us daily how you can help.
A few answers to the main topics that come up:
Can I help translating the app to my language?
Right now, we do not have any software to allow community based translations so we're not able to let users translate our app currently. However, you definitely help if you write us an email to firstname.lastname@example.org with mistakes you found in translations.
Can you make me a part of your team?
We are happy to work with you if you are available at least 20 hours a week and are willing to move to Berlin.
