I'd be happy to help set up a wiki. All it needs, realistically, is a server, a database, and something like Cloudflare for when it inevitably gets targeted for DDoS. And some configuration.

The real challenge is to do this with appropriate infosec. The best course of action is probably to ask someone that is already doing hosting for lemmy.ml if they would be interested in also hosting a wiki (we could run a donation drive to fund them) and to offer technical help. Would that be dessalines?

PS this is my new account of a longtime user, just rotating for infosec reasons.
