I'm back from the qepHom in Saarbrücken. Since it's kinda late now, I won't say more just now—hopefully later. But it was fun, and I hadn't forgotten quite as much as I had thought (though still enough).
Oh, and I got a present from my Secret Santa today: a book and a bookmark. Thanks! (There was a mistake in the address, though—the initial "2" of the five-digit postal code had wandered up to the end of the house number. Fortunately, the post office was able to deliver it anyway.)
