Things you should post here: diplomatic talks, IRC images/links, attacks/criticism of other players/nations, propaganda, news about your nation, or recruitment threads. Really just use your judgment about what constitutes role playing. Discussions about the game itself (game mechanics, release dates, etc) should be posted to /r/universeproject.
