This Saturday and Sunday, GMU email will be down completely, it seems. You won't be able to reach me or Alex through the usual email channel for that time. For me, use my gmail address those two days, if you wish. I don't want to put the address on-line but it's a lot like my gmu email address. Don't mail to it after this weekend, though, because I use it for storage and I don't check it regularly. Sorry for the inconvenience, reader email is for me a positive externality and I very much appreciate all of the great material you send in.
