Hello! I'm familiar with Nationstates so far as the mechanics of the game go, but I have never managed to get very far into any sort of community interaction. I have attempted to take part in the site's forums and ended up discouraged and berated for not being patient with new players.
The nationstate site forums are not a good example of a community IMO. A very extreme group of nations who enjoy intentionally causing drama for their own amusement.
