Dokuwiki is a flat file based wiki, and there is a discussion plugin for it, maybe that might give you some insight https://www.dokuwiki.org/plugin:discussion https://www.dokuwiki.org/plugin:discussion Though I think you could get the messages in a flat file (heck, BBSs did that since the 70s) though having a small db or some sort of link lists for user access, message indexing and such would probably add to the speed of the system.
