This hasn't hit my account either - of course, I'm freaked that it might, since I tend to earn enough to support two airline habits. I have no idea whose invite I originally accepted, but I've always been able to deposit in any of their airlines and hotels. I'm just crossing my fingers and checking every day to see if I get clobbered...made a quick deposit in my less-favored airline just in case.
My sympathy to everyone who's getting partially shut down...
