Exactly. Miraheze is also a good wiki platform, but I don't have any experience editing it (I'll figure it out). Account control would be the main thing. They would have to be people you've vetted on Hexbear or the like already, and then nobody else has edit access. That's how I've always done it on private company networks. Everyone on the network could access the company wiki, but only certain people could edit it.
Edit: While Miraheze is a public platform, and in my experience, pretty permissive concerning a wide variety of topics, yeah the site moderation would be something to consider. If you had access to a server you could setup a wiki suite on yourself that would be ideal. That costs money though.
I disagree. This is learned behavior. It's part of the cycle of violence that we all live with and all perpetuate. We are all raised in a cut-throat, dog-eat-dog, ruthless world where we're all taught to be mercenaries. You look out for you. Fuck social bonds, fuck family, fuck everything. We're taught that that's what's true, that that's how the world is. You look out for numero uno first and foremost. It's simply not true.
We are a collective species. The only reason you and are are sitting at a fucking computer sharing ideas instantaneously through the internet is because humanity collectively worked together for the shared interests of everyone. We are not evil and selfish. It is a learned behavior. It is a behavior we can un-learn. It is not inherent to our species.
Actual Edit: Fuck I just saw what /c/ I'm in. Carry on.
