>How to form a communist tribe or gang to protect yourself
Start today. If you can't find and networks with socialists today, how will that become easier during a crisis?
>Mutual aid and where to get it
lol mutual aid isn't something you simply get, it's something you are part of, something you help build. That's why it's called 'mutual'. You give, and you get. Again, it comes down with local networking, building connections and trust.
Many of the other questions really depend on local conditions. Some food which grows naturally near me won't survive near you. All I know is, these problems are so much easier to solve as a collective, that's why the first two steps matter.
