I’ve put in preliminary docs of what we need if people wish to move or mirror their mailing list on discourse.
I’m also starting a docs system using Discourse docs, to try to have a central loc where people can find how-tos about discourse, or to flag mailing list questions that have been solved as docs. That second part I’m still figuring out. Anyrate you’ll see a new link at the top that says “Docs” where these things will be easily accessible.
