So how exactly would you communicate, share files and information if you were organizing an uprising for example?

You can't always physically transport those files, and sometimes it may be more dangerous to do so (if you are wanted person for example). You also have issue if you are having those files transported cross border then you may get border issues (Philip Greewalds partner being help in UK). For speed and ease, it would have to be via the internet somehow. For higher security, it would have to be non-network connected computers and via USB. For even higher security it would be non-computer but then I would have to memorise everything and I don't have a photographic memory :(

I'm not sure what I would do in this case either tbh.
