As far as I am aware, it is not possible to have Discord post to the mailing list. The "mailing list" abilities of Discourse far outpace the standard mailing list that Apache has set up, due to the configuration options and formatting abilities, etc. I'll be talking to them about this as well to see if they have any suggestions.
As for these other requirements, I'm 100% confident that Discourse meets them. 1. If a linked email is adequate proof, this is already perfect. Discourse accounts are based on an email account which is publicly visible on all profiles. If Apache has it's own account system that is OAuth2 compatible, Discourse offers SSO capabilities for this as well. 2. All edits are visible to the public. For example, view this thread http://groovy.trydiscourse.com/t/improving-named-argument-support/15 and click the small pencil icon in the top right of the post. You will be able to see the diff between edits. This is of course on top of the fact that Discourse is completely open source and Apache is able to host it themselves. 3. I suppose this requirement is somewhat fulfilled because of the tight email integration that makes it behave nearly identical to current mailing lists. 4. Of course this is possible! 5. Yes, there are private categories on the forums. Thanks for having an open mind. -- Sent from: http://groovy.329449.n5.nabble.com/Groovy-Users-f329450.html
