Sharing whistleblower related documents

In the past months documents related to whistleblower support were exchanged via email and kept on the personal computers of volunteers. This is nor convenient nor secure. How can we improve the situation ?

You are welcome to host the documents on (or any other CHATONS provider) and I will send you credentials to do so. Note that by hosting documents on you implicitly trust the people who care for the service (myself and @fpoulain at the moment) to keep them safe. It is not an ideal situation (and you should try to find a way to not rely on any intermediary) but it is an improvement over keeping the documents or personal computers that are even less secure.
