So far, I am (trying) to use Roll20 for a play-by-post style WOD (Mage 20) game, due to mismatching Time Zones and schedules. I noticed though, that despite having different "boards" to push players onto, they are all interconnected to the same chat window. Sure, player-specific things can be whispered directly to one another, but I think having board-specific chats would be awesome. That way scenes can play out in different places without being bogged down.
