Why odd? They just have a very enthusiastic and dedicated fan base. I recall someone volunteering to help with something for free with something a while back and a ton of people jumped in to agree that they'd help the game for free.
But I highly, highly, highly doubt they're ignoring you, RT2. They just appear and disappear from the message board every now and then, and we assume it's because of a sudden update and development binge because we also assume that their lives revolve around making this game.
Which is perfectly cool with me.
