Per the title. CoC has a general forum. There might be things people want to discuss about the game other than just rules and deckbuilding...???
Why isn't there a "General" forum
Seeing as you're posting on a sub-forum of the general forum I find your question rather bemusing.
Anyway here's a link to the general forum: www.fantasyflightgames.com/edge_foros_temas.asp
IOW, the page that gets you to Off-Topic is the general forum with the various threads under the sub-forums.
