I forgot to say that I would accept people’s XP cash cards today as a mid-semester cash out. So how about this: if you want to cash in your cards mid-semester, you can do so next Thursday (right after fall break).

(Note that if you don’t turn them in mid-semester, there is no grade disadvantage: it just means the points won’t appear on the scoreboard until December, and it means that you have to keep track of your cards for that much longer.)
