I don't think it'd necessarily make it look like a ghost town! You can't start CR without general posts -- but both asgardeventide and exsilium even recommend when you're accepted that you create and link an IC inbox in your journal, and neither of them have a posting problem. While Exsilium is huge, yes, Asgard isn't that much larger than Exsilium. Posting still remains the #1 way in Para to get AC, either way. :)
